Bis{μ-2-[bis(pyridin-2-yl)methylidene]hydrazinecarbothioamidato}bis[bromidocopper(II)] methanol disolvate
In the centrosymmetric binuclear title compound, [Cu2Br2(C12H10N5S)2]·2CH3OH, the CuII ion adopts a slightly distorted square-pyramidal coordination geometry. The hydrazine carbothioamide moiety and one of the pyridyl rings together adopt an almost planar arrangement, with a maximum deviation of 0.052 (4) Å for the C atom of the thiourea moiety. There are two molecules of methanol solvent per complex in the asymmetric unit. The nonconventional intramolecular C—H⋯Br hydrogen bonds make the molecule more rigid, whereas the conventional N—H⋯N and O—H⋯Br intermolecular hydrogen-bonding interactions, supported with N—H⋯π interactions, establish a supramolecular linkage among the molecules in the crystal. An intermolecular C—H⋯O interaction is also present
(2E)-2-(3-Ethoxy-2-hydroxybenzylidene)hydrazinecarboxamide
The title compound, C10H13N3O3, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. A classical intramolecular O—H...N hydrogen bond is present. The two N atoms of the hydrazinecarboxamide unit are also involved in intermolecular N—H...O hydrogen bonds, with the O atom of the hydrazinecarboxamide group acting as the acceptor. Pairs of N—H...O hydrogen bond link the molecules into centrosymmetric dimers, which are linked by further N—H...O hydrogen bonds into chains along the b axis. The chains are linked by C—H...π interactions
Dichlorido{(2E)-2-[phenyl(pyridin-2-yl)methylidene]hydrazinecarbothioamide}cadmium(II) methanol monosolvate
In the title compound, [CdCl2(C13H12N4S)]·CH3OH, the coordination geometry of the CdII ion is slightly distorted square-pyramidal, as indicated by the τ index of 0.36 (8). The S atom, two N atoms from the pyridyl-azomethine moiety and one of the Cl atoms comprise the basal plane, while the other Cl atom occupies the apical position. The hydrazinecarbothioamide moiety adopts an E conformation with respect to the azomethine bond. The solvate molecule in the crystal lattice plays a major role in interconnecting adjacent molecules by means of O—H...Cl and N—H...O hydrogen-bonding interactions. A supramolecular three-dimensional architecture is sustained in terms of further N—H...Cl and C—H...Cl hydrogen-bonding interactions
