Co-crystallization of 1,3-

thiobarbituric
acid
(HDetba) with 2,2′-bipyridine (Bipy) and 1,10-phenanthroline (Phen) results in preparing a salt co-crystal, BipyH(Detba)(HDetba) (1), and the salt, PhenH(Detba)·H2O (2). The compounds are characterized by single–crystal and powder X–ray diffraction and TG-DSC. The nitrogen atoms of BipyH+ adopt a cis conformation and the N–C–C–N torsion angle is −17.3(1)º. 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).

, and BuOH is butanol-1, is determined (CIF file CCDC 1475273), and its IR spectrum is studied. The crystals are monoclinic: a = 10.7185(5), b = 21.985(1), c = 12.7235(7) Å, β = 92.196(2)°, V = 2996.1(3) Å3, space group P21/c, Z = 2. The Co2+ ions in compound I are joined in pairs by bridging ligands μ2-Detba–−O,O'. In addition, each of them is linked through the O atoms to one terminal Detba–ion and two BuOH molecules to form a trigonal bipyramid СоО5. Hydrogen bonds O–H···O formed by BuOH and Detba– join the binuclear complexes into an infinite chain. The data of IR spectroscopy are consistent with the results of X-ray diffraction analysis.

(HDetba), barbiturate-bridged 2D Mn(II) polymer [Mn(H2O)2(Detba)2] (1), trinuclear [Mn3(H2O)10(Detba)6] (2) and discrete molecular [Mn(H2O)4(Detba)2]·H2O (3) are synthesized and structurally characterized by the X-ray single crystal technique. In 1–3, the Detba− ions are coordinated to Mn(II) only through O atoms with manganese ions in the octahedral environment. In 1, the Mn(II) ion is coordinated by four μ2 bridge Detba− ions and two terminal H2O molecules. In 2, the Mn1 ion is coordinated by three terminal H2O molecules, two terminal and one μ2 bridge Detba− ion, and Mn2 is connected with two μ2-Detba− ions and four H2O molecules. In 3, the Mn(II) ion is coordinated by two terminal Detba− ions and four terminal H2O molecules. There are intermolecular hydrogen bonds O–H⋯O, O–H⋯S in the structures of 1–3 which form the 3D networks. Structure 2 is stabilized by the π–π interaction. The compounds thermal decomposition comprises dehydration steps and the organic ligand oxidation.

Аннотация:
Two new isostructural complexes, [Ca(H2O)2(μ2-Detba-O,O′)2]n (1) and [Sr(H2O)2(μ2-Detba-O,O′)2]n (2) (HDetba = 1,3-
diethyl
-2-
thiobarbituric
acid
), were synthesized and characterized by single-crystal and powder X-ray diffraction analysis, TG-DSC, FT-IR, and emission spectroscopy. The single-crystal X-ray diffraction data revealed that 1 and 2 are polymeric where M2+ (M = Ca, Sr) is a six-coordinate octahedral binding four Detba− ions and two water molecules. The octahedra are linked through bridging Detba− ions forming a 2-D layer. Two intermolecular hydrogen bonds O–H…S in the crystal form a 3-D net. The comparison of M(Detba)2 and M(Htba)2 (H2tba = 2-
thiobarbituric
acid
) structures showed that the coordination number of metals in M(Detba)2 does not exceed six and there are no π–π interactions, unlike compounds with Htba−; Detba− ions are only bridges in HDetba coordination compounds. Thermal decomposition of 1 and 2 includes dehydration, which mainly ends at 200 °C, and organic ligand oxidation at 300–350 °C with a release of CO2, SO2, H2O, NH3, and isocyanate. Upon excitation at 220 nm, 1 and 2 exhibit an intense emission maximum at 557 nm.

(C8H12N2O2S) is synthesized and its structure is determined by X-ray crystallography. The crystals of I are triclinic: a = 11.0205(2) Å, b = 11.8811(3) Å, c = 12.7312(2) Å, α = 100.933(1)°, β = 109.704(1)°, γ = 101.161(1)°, V = 1479.88(5) Å3, space group P-1, Z = 2. Each of three independent DETBA- ions is a bridging μ2-O,O′-coordinated ligand. The coordination polyhedron of Eu(III) is a distorted octahedron. Bridging DETBA- organize the octahedra into an infinite two-dimensional layer. The structure contains intramolecular hydrogen bonds but intermolecular hydrogen bonds and the π-π interaction are absent. The results of IR spectroscopy and photoluminescence agree with the single crystal X-ray diffraction data. The main product of the thermal decomposition of I at 900°C is oxysulfate Eu2O2SO4. © 2016 Pleiades Publishing, Ltd.

The outer-sphere Detba- ions and H2O molecules participate in O-H?(O/S) intermolecular hydrogen bonds which form the 2D layer.

In Li(I) and Na(I) complexes, the DETBA− ion is in cis-configuration and, in the K(I) complex, this ion is in trans-configuration. The reason for the transformation from cis- to trans-configuration has been rationalized.

(C8H11N2O2S, Hdetba) with Rb+, Cs+, Tl+ and NH4+ ions were prepared by Hdetba neutralization with the metal carbonates or ammonium hydroxide in aqueous solution. The colorless crystals have been investigated using X-ray diffraction techniques, differential scanning calorimetry, thermogravimetry and infrared spectroscopy. The coordination compounds of MDetba with M = Rb, Cs and Tl crystallize in the orthorhombic space group P212121, but compound NH4Detba crystallizes in the triclinic space group P1¯. The MDetba structures were compared at the molecular and supramolecular levels. The Detba- ion in the NH4+ compound forms conformer (A) with two
diethyl
groups on one side of the ion ring, whereas the Detba- ion in the Rb(I), Cs(I) and Tl(I) compounds forms conformer (B) with two
diethyl
groups on different sides of the ring. The results of IR spectroscopy and thermal analysis are consistent with the X-ray data. © 2015 Elsevier Ltd.
