The title compound, [CdBr(2)(C(13)H(12)N(4)O)], was obtained from the reaction of Cd(NO(3))(2)·4H(2)O with meth-yl(pyridin-2-yl)methanone picolinoylhydrazone and sodium bromide. The Cd(2+) cation is ligated by one O atom and two N atoms of the tridentate ligand and two bromide anions, forming a Br(2)CdN(2)O polyhedron with a distorted trigonal-bipyramidal coordination geometry. In the crystal, non-classical C-H⋯Br hydrogen bonds are observed. In addition, π-π stacking inter-actions [centroid-centroid distance = 3.7455 (19) Å] contribute to the stabilization of the crystal structure.

The title compounds, [CdBr(CHNO)]·CHOH, (I), and [CdI(CHNO)], (II), are cadmium bromide and cadmium iodide complexes of the ligand ()-'-(pyridin-2-yl-methyl-ene)picolinohydrazide. Complex (I) crystallizes as the methanol monosolvate. In both compounds, the Cd cation is ligated by one O atom and two N atoms of the tridentate ligand, and by two bromide anions forming a BrNO penta-coordination sphere for (I), and by two iodide anions forming an INO penta-coordination sphere for (II), both with a distorted square-pyramidal geometry.

In the mol-ecule of the title compound, [CdBr2(C14H12N2)(C2H6OS)], the Cd(II) atom is five-coordinated in a distorted trigonal-bipyramidal configuration by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand, one O atom from a dimethyl sulfoxide ligand and two Br atoms. In the crystal, π-π contacts between the pyridine and benzene rings [centroid-centroid distances = 3.710 (5), 3.

In the title compound, [CdBr(2)(C(11)H(10)N(2))(C(2)H(6)OS)], the Cd(II) atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two N atoms from a 6-methyl-2,2'-bipyridine ligand, one O atom from a dimethyl sulfoxide ligand and two Br atoms. An intra-molecular C-H⋯O hydrogen bond occurs. The crystal structure is stabilized by C-H⋯Br hydrogen bonds and π-π contacts between the pyridine rings [centroid-centroid distances = 3.

In the title compound, [CdBr(2)(C(12)H(12)N(2))(C(2)H(6)OS)], the Cd(II) atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two N atoms from one 4,4'-dimethyl-2,2'-bipyridine (DMBP) ligand, one O atom from a dimethyl sulfoxide (DMSO) ligand and two Br atoms. A weak intra-molecular C-H⋯O hydrogen bond occurs between the DMBP and DMSO ligands. π-π stacking between pyridine rings [centroid-centroid distances = 3.
