RESUMEN
In the title complex, [CuBr(2)(C(19)H(15)N(3)O(2))], the metal ion is coordinated by the N,N',O-tridentate 2-hydr-oxy-N'-[phen-yl(2-pyrid-yl)methyl-ene]benzohydrazide ligand and two bromide ions, resulting in a distorted CuN(2)OBr(2) square-based pyramidal coordination geometry with one bromide ion in the apical site. An intra-molecular N-Hâ¯O hydrogen bond occurs in the ligand. In the crystal, mol-ecules are connected by inter-molecular C-Hâ¯O, C-Hâ¯Br and O-Hâ¯Br inter-actions.
RESUMEN
In the title complex, [Ni{N(CN)(2)}(2)(C(7)H(9)NO)(2)], the Ni(II) ion (site symmetry ) adopts a distorted trans-NiO(2)N(4) octa-hedral geometry. In the crystal, inter-molecular O-Hâ¯N hydrogen bonds link the mol-ecules, forming a chain along the c axis.
RESUMEN
The title compound, C(8)H(9)N(3)S, contains two mol-ecules in the asymmetric unit. One mol-ecule is close to being planar (r.m.s. deviation from the mean plane = 0.06â Å for the non-H atoms), while the other exhibits a dihedral angle of 21.7â (1)° between the benzene ring and the mean plane of the thio-semicarbazone unit. Inter-molecular N-Hâ¯S hydrogen bonds link the mol-ecules into layers parallel to the (010) plane.
