Аннотация: Reactions of Fe-2(CO)(9) with Cp(CO)(2)Mn=C=CHPh (1) and Cp(CO)(PPh3)Mn=C=CHPh (3) gave the heterometallic trimethylenemethane complexes eta(4)-{C[Mn(CO)(2)Cp](CO)CHPh}Fe(CO)(3) (2) and eta(4)-{C[Mn(CO)(PPh3)Cp](CO)CHPh}Fe(CO)(3) (4), respectively. The formation of the benzylideneketene [PhHC=C=C=O] fragment included in complexes 2 and 4 occurs via intramolecular coupling of the carbonyl and vinylidene ligands. The structures of 3 and 4 were determined by single crystal XRD methods. The influence of the nature of the L ligands at the Mn atom on the structural and spectroscopic characteristics of eta(4)-{C[Mn(CO)(L)Cp](CO)CHPh}Fe(CO)(3) (L = CO (2), PPh3 (4)) is considered. According to the VT H-1 and C-13 NMR spectra, complex 2 reversibly transforms in solution into mu-eta(1):eta(1)-vinylidene isomer Cp(CO)(2)MnFe(mu-C=CHPh)(CO)(4) (2a), whereas complex 4 containing the PPh3 ligand is not able to a similar transformation.

Кл.слова (ненормированные):
active topsoil -- complex dielectric constant, Arctic tundra -- freezing/thawing soil -- radar backscattering coefficient -- soil temperature
Аннотация: In this article, the possibility of measuring the average temperature in the active topsoil of the Arctic tundra from the temperature dependence of the radar backscattering coefficient is theoretically studied. The radar backscattering coefficient is simulated by the small perturbation method at a frequency of 1.26 GHz of radars placed onboard ALOS-2 and SMAP satellites. In simulation, the soil density, surface roughness, and temperature and moisture profiles measured in situ at the biosphere station Franklin Bluffs, Alaska (69В°39? N, 148В°43? W), from August 1, 2000 to July 1, 2001 were used. The soil permittivity was calculated for the generalized temperature-dependent refractive mixing dielectric model for organic rich soil whose sample was taken on the Alaska North Slope (68В°38?N, 149В°35?W). This model allows the complex dielectric constant of moist thawed and frozen soil to be calculated at temperatures in the range from -30В°S{cyrillic} to +25В°S{cyrillic}. It is demonstrated that the radar backscattering coefficient is correlated with the topsoil temperature with the error less than 5.7В°S{cyrillic} during the entire period of freezing and thawing.

Аннотация: In this letter, a multirelaxation generalized refractive mixing dielectric model (GRMDM) for moist soil is proposed and substantiated in the frequency range from 0.04 to 26.5 GHz. This model is based on the methodology of a single-relaxation GRMDM which accounts only for the dipole relaxation of water molecules in the gigahertz frequency range. The proposed multirelaxation GRMDM takes into account both the dipole (Debye) and ionic (Maxwell-Wagner) relaxations of soil water molecules. For this purpose, it uses a two-frequency Debye relaxation equation for the dielectric spectra of bound water. The spectroscopic parameters of the multirelaxation GRMDM were derived by fitting the spectra calculated by this model to the respective measured ones. The main advantage of this model is that it predicts the complex dielectric constant of moist soils throughout the megahertz and gigahertz frequency ranges with the same error as the single-relaxation GRMDM does only in the gigahertz range.

Аннотация: The structures of the LiI and NaI salts of 2-thiobarbituric acid (2-sulfanylidene-1-3-diazinane-4,6-dione, H 2TBA) have been studied. μ-Aqua-octaaquabis(μ-2- thiobarbiturato-κ2 O:O′)bis(2-thiobarbiturato-κO) tetralithium(I) dihydrate, [Li4(C4H3N 2O2S)4(H2O)9]·2H 2O, (I), crystallizes with four symmetry-independent four-coordinated LiI cations and four independent HTBA- anions. The structure contains two structurally non-equivalent LiI cations and two non-equivalent HTBA- anions (bridging and terminal). Eight of the coordinated water ligands are terminal and the ninth acts as a bridge between LiI cations. Discrete [Li4(HTBA)4(H2O)9] ·2H2O complexes form two-dimensional layers. Neighbouring layers are connected via hydrogen-bonding interactions, resulting in a three-dimensional network. Poly[μ2-aqua-tetraaqua(μ4-2- thiobarbiturato-κ4 O:O:S:S)(μ2-thiobarbiturato- κ2 O:S)disodium(I)], [Na2(C4H 3N2O2S)2(H2O) 5] n , (II), crystallizes with six-coordinated NaI cations. The octahedra are pairwise connected through edge-sharing by a water O atom and an O atom from the μ4-HTBA- ligand, and these pairs are further top-shared by the S atoms to form continuous chains along the a direction. Two independent HTBA- ligands integrate the chains to give a three-dimensional network. © 2013 International Union of Crystallography.

Аннотация: The interaction between Cp(CO)2ReCCHPh (1) and CuCl results in the new heterometallic μ-vinylidene complex [Cp(CO)2ReCu(μ2-CCHPh)(μ2-Cl)]2 (2) characterized earlier by IR and 1H, 13C NMR spectra. The molecular structure of compound 2 has been determined by X-ray diffraction analysis, revealing a dimer structure with two binuclear fragments linked to each other by asymmetric chloride bridges. The electrochemical behavior of 2 in acetonitrile was studied by cyclic voltammetry at a Pt-electrode.

Ceftriaxone lead(II) complex -- DFT -- IR spectroscopy -- TGA -- Antibacterial screening
Аннотация: A Pb(II) complex with ceftriaxone (H2Ceftria) antibiotic was synthesized by reaction of ceftriaxone disodium salt (hemi)heptahydrate with lead nitrate in water–ethanol medium. The complex was characterized on the basis of complexometric titration, spectrophotometric and thermogravimetric analyses, capillary electrophoresis, IR, Raman and UV–vis spectroscopies, and density functional theory calculations. Pb(II) is five-coordinate with distorted square pyramidal geometry. The coordination of Ceftria2− to Pb(II) occurs through N and O of the triazine, lactam carbonyl, carboxylate, and amine groups. The antibacterial activity study showed that Klebsiella pneumoniae is resistant to [Pb(Ceftria)]·3H2O. The antibacterial activity of [Pb(Ceftria)]·3H2O against Staphylococcus aureus is reduced compared with ceftriaxone. In contrast, the antibacterial activity of [Pb(Ceftria)]·3H2O against Escherichia coli is 28% higher than that of ceftriaxone antibiotic.

    Symmetry breaking in open quantum nonlinear systems / A. F. Sadreev [et al.] // Nonlinear phenomena in complex systems: from nano to macro scale : Springer, 2015. - P. 235-252. - (NATO science for peace and security series C: Environmental security)DOI 10.1007/978-94-017-8704-8_17 . - ISBN 978-94-017-8704-8. - ISBN 978-94-017-8703-1
   Перевод заглавия: Нарушение симметрии в открытых квантовых нелинейных системах
Аннотация: We consider symmetry breaking in the simplest open quantum nonlinear systems such as dimer and plaquette of four nonlinear sites coupled with linear tight-binding wires. If the solution is stationary, the total Hilbert space can be projected into the inner states of the dimer or plaquette by the Feshbach procedure. That derives a nonlinear analogue of the Lippmann-Schwinger equation with injected wave as a source. By neglecting radiation shifts the Lippmann-Scwinger equation limits to the coupled mode theory equations widely used in optics. We show three scenarios for the transmission through the nonlinear quantum systems. The first one inherits the linear case and preserves the symmetry. In the second scenario the symmetry is broken because of different intensities at the dimer sites. In the third scenario the intensities at the sites are equaled but phases of complex wave function are different. That results in a vortical power flow between the nonlinear sites similar to the DC Josephson current. We show how the phenomenon of symmetry breaking can used for switching of outputs symmetrically coupled to the quantum dimer . Also we reveal a domain in the parameter space where none of stationary solutions exist. As a result injection of a monochromatic symmetric wave gives rise to emission of nonsymmetric satellite waves with energies different from the energy of the incident wave. Thus, the response exhibits non monochromatic behavior.

reconstructive phase transition -- ammonium heptafluorotitanate -- order-disorder transition
Аннотация: An unusual phase transition P4/mnc →Pa3 has been detected after cooling the (NH4)3TiF7 compound. Some TiF6 octahedra, which are disordered in the room-temperature tetragonal structure, become ordered in the low-temperature cubic phase due to the disappearance of the fourfold axis. Other TiF6 octahedra undergo large rotations resulting in huge displacements of the F atoms by 1.5-1.8 Å that implies a reconstructive phase transition. It was supposed that phases P4/mbm and Pm3m could be a high-temperature phase and a parent phase, respectively, in (NH4)3TiF7. Therefore, the sequence of phase transitions can be written as Pm3m → P4/bm → P4/mnc → Pa3. The interrelation between (NH4)3TiF7, (NH4)3GeF7 and (NH4)3PbF7 is found, which allows us to suppose phase transitions in relative compounds.

Аннотация: Neodymium complex [Nd(HTBA)2(C2H3O2)(H2O)2]n·2nH2O (1) (H2TBA = 2-thiobarbituric acid, C4H4N2O2S) has been synthesized in an aqueous solution at 80–90 °C. The crystal structure of 1 has been determined by the Rietveld method in space group P21/n, a = 8.5939(2), b = 22.9953(5), c = 10.1832(2) Å, β = 112.838(1)°, Z = 4, and R = 0.0181. In 1, the Nd(III) is coordinated by four μ2-HTBA– ions through O, three oxygens from two μ2-η2 : η1-bridging CH3COO– anions, and two terminal waters with a tri-capped trigonal prism structure. The prisms form an edge-contact pair through two O from two acetates. The pairs are connected by HTBA– and form a 3-D framework. The principle product of thermal decomposition of 1 at >750 °C is Nd2O2SO4 (2). The crystal structure of 2 has been obtained in space group I222, a = 4.1199(4), b = 4.2233(4), c = 13.3490(12) Å, Z = 2, and R = 0.0246. The structure is related to an orthorhombic structure type of M2O2SO4 (M = Ln) compounds. In 2, the Nd3+ is coordinated by six oxygens in a trigonal prism. Each NdO6 prism links with two SO4 tetrahedra by nodes, with four other NdO6 prisms by edges, and with four other NdO6 prisms by nodes, and the units form the 3-D frame. In the frame, the layers of SO4 tetrahedra are alternated by two NdO6 prism layers.
