Заглавие : A Challenge toward novel quaternary sulfides SrLnCuS3 (Ln = La, Nd, Tm): Unraveling synthetic pathways, structures and properties
Место публикации : Int. J. Mol. Sci. - 2022. - Vol. 23, Is. 20. - Ст.12438. - ISSN 14220067 (ISSN), DOI 10.3390/ijms232012438

Аннотация: We report on the novel heterometallic quaternary sulfides SrLnCuS3 (Ln = La, Nd, Tm), obtained as both single crystals and powdered samples. The structures of both the single crystal and powdered samples of SrLaCuS3 and SrNdCuS3 belong to the orthorhombic space group Pnma but are of different structural types, while both samples of SrTmCuS3 crystallize in the orthorhombic space group Cmcm with the structural type KZrCuS3. Three-dimensional crystal structures of SrLaCuS3 and SrNdCuS3 are formed from the (Sr/Ln)S7 capped trigonal prisms and CuS4 tetrahedra. In SrLaCuS3, alternating 2D layers are stacked, while the main backbone of the structure of SrNdCuS3 is a polymeric 3D framework [(Sr/Ln)S7]n, strengthened by 1D polymeric chains (CuS4)n with 1D channels, filled by the other Sr2+/Ln3+ cations, which, in turn, form 1D dimeric ribbons. A 3D crystal structure of SrTmCuS3 is constructed from the SrS6 trigonal prisms, TmS6 octahedra and CuS4 tetrahedra. The latter two polyhedra are packed together into 2D layers, which are separated by 1D chains (SrS6)n and 1D free channels. In both crystal structures of SrLaCuS3 obtained in this work, the crystallographic positions of strontium and lanthanum were partially mixed, while only in the structure of SrNdCuS3, solved from the powder X-ray diffraction data, were the crystallographic positions of strontium and neodymium partially mixed. Band gaps of SrLnCuS3 (Ln = La, Nd, Tm) were found to be 1.86, 1.94 and 2.57 eV, respectively. Both SrNdCuS3 and SrTmCuS3 were found to be paramagnetic at 20-300 K, with the experimental magnetic characteristics being in good agreement with the corresponding calculated parameters.

Заглавие : An effect of reduced S-rich fluids on diamond formation under mantle-slab interaction
Место публикации : Lithos. - 2019. - Vol. 336-337. - P.27-39. - ISSN 00244937 (ISSN), DOI 10.1016/j.lithos.2019.03.027
Примечания : Cited References: 73. - This work was supported by the Russian Science Foundation under Grant No. 14-27-00054 and a state assignment of IGM SB RAS. The authors thank S. Ovchinnikov for his assistance in implementation of the Mossbauer spectroscopy measurements.
Аннотация: Experimental study, dedicated to understanding the effect of S-rich reduced fluids on the diamond-forming processes under subduction settings, was performed using a multi-anvil high-pressure split-sphere apparatus in Fe3C-(Mg,Ca)CO3-S and Fe0-(Mg,Ca)CO3-S systems at the pressure of 6.3 GPa, temperatures in the range of 900–1600 °C and run time of 18–60 h. At the temperatures of 900 and 1000 °C in the carbide-carbonate-sulfur system, extraction of carbon from cohenite through the interaction with S-rich reduced fluid, as well as C0-producing redox reactions of carbonate with carbide were realized. As a result, graphite formation in assemblage with magnesiowüstite, cohenite and pyrrhotite (±aragonite) was established. At higher temperatures (≥1100 °C) formation of assemblage of Fe3+-magnesiowüstite and graphite was accompanied by generation of fO2-contrasting melts - metal-sulfide with dissolved carbon (Fe-S-C) and sulfide-oxide (Fe-S-O). In the temperature range of 1400–1600 °C spontaneous diamond nucleation was found to occur via redox interactions of carbide or iron with carbonate. It was established, that interactions of Fe-S-C and Fe-S-O melts as well as of Fe-S-C melt and magnesiowüstite, were С0-forming processes, accompanied by disproportionation of Fe. These resulted in the crystallization of Fe3+-magnesiowüstite+graphite assemblage and growth of diamond. We show that a participation of sulfur in subduction-related elemental carbon-forming processes results in sharp decrease of partial melting temperatures (~300 °C), reducting the reactivity of the Fe-S-C melt relatively to FeC melt with respect to graphite and diamond crystallization and decrease of diamond growth rate.

Аннотация: Off-stoichiometric manganese monosulfides alpha -MnxS (1 less than or equal to x less than or equal to 1.25) are synthesized, and their crystal structure and magnetic properties are studied in the 4.2- to 300-K range. The compounds have a NaCl fcc lattice. Increasing the manganese ion concentration x in the antiferromagnetic semiconductors alpha -MnxS is found to result in concentration- (x(c) similar to 1.05) and temperature-driven (T-c similar to 50 K) magnetic transitions from the antiferromagnetic to ferromagnetic state, with the cubic structure remaining unchanged.

Аннотация: The permittivity of TmxMn1–xS (0 < x < 0.15) solid solutions is measured in the frequency range of 102–106 Hz at temperatures of 300–500 K in magnetic fields of up to 12 kOe. The migration and relaxation conductivity contributions to the electric polarization are established. The relaxation time and activation energy are calculated using the Debye model. A decrease in the capacitance and relaxation time in a magnetic field is observed. The electron polarization relaxation channel provided by recombination of the electron–hole pairs is found using the infrared spectroscopy investigations.

Заглавие : Crystal chemistry and structure of expected compounds A2BX4. II. Oxides, selenides, and sulfides 061A2B6+X4 2- and 080A2 2+B4+X4 2-.
Место публикации : Sov. Phys.: Crystallogr. - 1985. - Vol. 30, Is. 5. - P.533-535; \b Crystallography Reports; \b Kristallografiya
Аннотация: Predictions of A2BX4 compounds for compositions 071A2 +B6+X4 2- with type structures of K2MgF4, beta -K2SO4, spinel, olivine, thenardite, phenacite, Sr2PbO4, and Pb3O4 are presented. K2MgF4 type structures are known and probable only in oxides and sulphides with hexavalent uranium because their formation is limited by the size of the hexavalent B cation. Structures of the beta -K2SO4 type are stable in compounds with large A cations. Among the sulphides with 076A2 +B6+X4 2-, the spinel crystal structure is as yet unknown, but is most probable in compounds with A+ = Li, Na, Ag, and with B6+ = Mo, W, and U. The olivine type structure is known only in Ag2CrO4, and no new compounds with this structure are expected to be found. A phenacite structure is probable only in three new oxides and in some sulphides with Li as A+. A thenardite type structure is probable in oxides with B6+ = Fe and Mn, but sulphides are unlikely. For 076A2 2+B4+X4 2- compounds with large A2+ ions and B4+ ions with radii from 0.57 A to RB 0.48RA + 0.11, a K2MgF4 structure would exist. For even larger A ions, the Sr2PbO4 structure would exist. In oxides with cations A2+ = Pb and Sn, compounds with Pb3O4 type structures are probable.-D.F.P.

Аннотация: Regions of the existence of sulfide Gd (x) Mn1 - x S and selenide Ti (x) Mn1 - x Se solid solutions have been identified. Their electrical and thermoelectric properties have been studied in the temperature range 80-900 K. It has been established that the substitution of Gd2+ and Ti2+ ions for Mn2+ cations initiates reversal of the type of charge carrier with respect to the starting compounds MnS and MnSe. The cation substitution in solid solutions brings about a change from the hole conduction (alpha 0) characteristic of the manganese monosulfide and monoselenide to the electronic conduction (alpha 0).

Аннотация: In the present work, we report on the synthesis of Sc2S3, ScCuS2 and BaScCuS3 powders using a method based on oxides sulfidation and modification of their properties. The crystal structures and morphology of samples are verified by XRD and SEM techniques. Thermal stability has been studied by DTA which has revealed that Sc2S3 decomposes to ScS through melting at 1877 K. ScCuS2 and BaScCuS3 melt incongruently at temperatures of 1618 K and 1535 K, respectively. The electronic structure calculations show that the investigated compounds are semiconductors with indirect band gap (Eg). According to the diffuse reflection spectroscopy, Sc2S3, ScCuS2 and BaScCuS3 are wide-bandgap semiconductors featured the Eg values of 2.53 eV, 2.05 eV and 2.06 eV, respectively. The band gap decreases with the introduction of copper (I) and barium cations into the crystal structure of the compounds. Variation of local structure has been verified by Raman and infrared spectroscopy. The calculated vibrational modes of ScCuS2 correspond to CuS4 and Sc−S layer vibrations, even though ScS6 octahedra-like structural units can be found in the structure.
