Barbituric and thiobarbituric acids -- Ciprofloxacin -- Infrared spectroscopy -- Salt cocrystal -- Thermal stability -- X-ray diffraction
Аннотация: Ciprofloxacin (CfH, C17H18FN3O3) crystallizes with 2-thiobarbituric (H2tba) and barbituric acid (H2ba) in the aqueous solution to yield salt CfH2(Htba)·3H2O (1), salt cocrystal CfH2(Hba)(H2ba)·3H2O (2), and salt CfH2(Hba)·H2O (3). The compounds are structurally characterized by the X-ray single-crystal diffraction. The numerous intermolecular hydrogen bonds N–H⋯O and O–H⋯O formed by water molecules, Htba−/Hba− and CfH2+ ions, and H2ba molecules stabilize the crystal structures of 1 to 3. Hydrogen bonds form a 2D plane network in the salts of 1 and 3 and a 3D network in the salt cocrystal of 2. There are different π-π interactions in 1 to 3. The compounds have been characterized by powder X-ray diffraction, thermogravimetry/differential scanning calorimetry, and Fourier transform infrared spectroscopy. The compounds dehydration ends at 130°C to 150°C, and their oxidative decomposition is observed in the range of 250°C to 275°C.

    Строение гидратов комплексов металлов с барбитуровыми кислотами / Николай Николаевич Головнев, М. С. Молокеев, M. K. Лесников // Журн. СФУ. Химия. - 2017. - Т. 10, № 3. - С. 401-415 ; J. Sib.

Кл.слова (ненормированные):
барбитуровые кислоты -- ионы металлов -- комплексы -- гидраты -- структура -- barbituric acids -- metal ions -- complexes -- hydrates -- structure
Аннотация: Обобщены данные о синтезе и структуре комплексов металлов с барбитуровой (H2ba), тиобарбитуровой (H2tba) и 1,3-диэтил-2-тиобарбитуровой (HDetba) кислотами, в состав которых входит различное количество координированных молекул воды. В зависимости от условий из водного раствора кристаллизуются соединения состава [M(H2O)n−kLm]0∙pH2O (Mm+ – ион металла; L− = Hba−, Htba− и Detba−; k≥0, p≥0). Образование нейтральных комплексов [M(H2O)n−kLm]0∙pH2O, содержащих разное количество координированных молекул воды (n−k), имеет место в случае лигандов L− с потенциально разной дентатностью и/или с мостиковым способом координации. Кристаллизация нескольких гидратов [M(H2O)n−kLm]0∙pH2O также ожидается, если в них молекулы воды могут быть как концевыми, так и мостиковыми лигандами, а центральные ионы, например, щелочноземельных металлов, легко образуют разные координационные полиэдры. Синтез новых гидратов может существенно расширить круг доступных соединений, в том числе и с потенциально полезными функциональными свойствами.
Data on the synthesis and structure of metal complexes with barbituric (H2ba), thiobarbituric (H2tba) and 1,3-diethyl-2-thiobarbituric (HDetba) acids, which include a different number of coordinated water molecules, are summarized. Depending on the conditions, compounds of the composition [M(H2O)n−kLm]0∙pH2O (Mm+ – metal ion; L− = Hba−, Htba− и Detba−; k≥0, p≥0) crystallize from the aqueous solution. The formation of neutral complexes of [M(H2O)n−kLm]0∙pH2O containing different amounts of coordinated water molecules (n-k) occurs in the case of L− ligands with potentially different dentateness and/or bridging coordination. Crystallization of several hydrates [M(H2O)n−kLm]0∙pH2O is also expected if water molecules can be both terminal and bridged ligands in them, and central ions, for example, of alkaline earth metals, easily form different coordination polyhedra. Synthesis of new hydrates can significantly expand the range of available compounds, including potentially useful functional properties.

Аннотация: The lithium(I) catena-diaquabarbiturate complex [Li(H2O)2(HBA–O,O′)]n (I), where Н2ВА is barbituric acid, has been structurally characterized by X-ray diffraction (CIF file CCDC no. 1447689), and its thermal decomposition and IR spectrum have been studied. Crystals of complex I are monoclinic, a = 6.4306(7) Å, b = 16.720(1) Å, c = 7.1732(8) Å, β = 108.253(4)°, V = 732.5(1) Å3, space group P21/c, and Z = 4. One independent μ2-bridging HBA– ligand is coordinated to two Li(I) ions via the two oxygen atoms of C4(6)=O carbonyl groups. Each Li+ ion is linked with two μ2-HBA– ions and two terminal water molecules at tetrahedron vertices. μ2-HBA– ions link tetrahedra into a chain. The structure is stabilized by multiple hydrogen bonds and π–π-interaction between HBA–. The shift of ν(C=O) vibration bands in the IR spectrum of complex I in comparison with Н2ВА towards lower frequencies agrees with the coordination of HBA– via oxygen atoms. The dehydration of complex I occurs in two stages in the regions of 100–150 and 150–240°C.

Аннотация: The structure of levofloxacinium 2-thiobarbiturate trihydrate LevoH 2 + Htba–·3H2O (I) (LevoH is levofloxacin, H2tba is 2-thiobarbituric acid) is determined (CIF file CCDC No. 1547466); its thermal decomposition and IR spectrum are studied. The crystals of I are triclinic: a = 8.670(1) Å, b = 9.605(1) Å, c = 15.786(2) Å, α = 89.144(5)°, β = 88.279(5)°, γ = 76.068(5)°, V = 1275.4(3) Å3, space group P1, Z = 2. The unit cell of I contains two LevoH 2 + ions, two Htba– ions, and six H2O molecules. The absolute structure of the crystal and the configuration of the chiral center in a levofloxacin molecule S are determined. Experiments for generating the second optical harmonics gave a positive result. Intermolecular hydrogen bonds (HBs) N–H···O and O–H···O in I form a bilayer system along the ab diagonal with hydrophilic moieties within a layer and hydrophobic moieties directed outward. The structure is stabilized by multiple HBs and the π–π interaction between the Htba–and LevoH 2 + ions and between the LevoH 2 + ions.

Barbituric acid -- 1,10-Phenanthroline complexes -- X-ray diffraction -- Thermal decomposition -- Infrared spectroscopy
Аннотация: Two nickel(II) and cobalt(II) complexes with phenanthroline, [Ni(Phen)(H2O)3Br]Br (1) and [Co(Phen)2(H2O)2](Hba)2·2H2O (2), Phen = 1,10-phenanthroline and Hba− = barbiturate anion, were synthesized and characterized by powder XRD, TGA and FT-IR. Their structures were determined by single crystal X-ray diffraction techniques. The Ni2+ ion is coordinated by two N atoms of Phen molecule, Br− ion and three H2O molecules forming an octahedron. Uncoordinated and coordinated Br− ions are connected with water molecules by OH⋯Br intermolecular hydrogen bonds with the formation of a 2D plane network which is extended into a 3D network by π−π stacking interactions. The [Co(Phen)2(H2O)2]2+ cation contains a six-coordinated cobalt atom chelated by two Phen ligands and two aqua ligands in the cis arrangement. NH⋯O, OH⋯O and CH⋯O intermolecular hydrogen bonds form a 3D net. NH⋯O hydrogen bonds form the infinite chains of Hba–. In addition, coordinated Phen molecules and lattice water molecules are linked via CH⋯OW hydrogen bonds to form infinite zigzag chains. These different chains are connected by OWH⋯O hydrogen bonds. π−π interaction plays an important role in the stabilization of structures 1–2. FT-IR, TGA, the diffuse reflectance, and UV–Vis spectra were also used to characterize these compounds.

There are six intermolecular hydrogen bonds O–H⋯O, N–H⋯O, C–H⋯O and C–H⋯S in (1) which form a 2D plane network. One Detba– ion and one HDetba molecule form a pair by means of O–H⋯O hydrogen bonds. Detba− anions in (2) do not form dimers, they are connected by N–H⋯O, C–H⋯S, and C–H⋯O hydrogen bonds only with PhenH+ cations and water molecules which form a 3D net. Different π−π interactions between the rings are found in (1)−(2).

Аннотация: New compounds of sparfloxacin (C19H22F2N4O3, SfH) and levofloxacin (C18H20FN3O4, LevoH) with mineral acids, namely, sparfloxacinium bromide (SfH · HBr, I) and levofloxacindium diperchlorate (LevoH · 2HClO4, II), have been synthesized and characterized by X-ray diffraction. Crystallographic data are a = 7.7151(7) Å, , b = 26.109(3) Å,с = 10.008(1) Å, β = 103.556(1)°, V = 1959.7(3) Å3, space group P21/n, Z = 4 for I and a = 9.727(6) Å, b = 20.440(12) Å, с = 12.286(7) Å, β = 104.327(8)°, V = 2367(2)Å3, space group P21, Z = 4 for II. The structures of these compounds are stabilized by intra- and intermolecular hydrogen bonds and π–π interaction between SfH2 + or LevoH3 2+ ions. © 2016, Pleiades Publishing, Ltd.
