Dibromido{N'-[1-(pyridin-2-yl)ethyl-idene]picolinohydrazide-?(2)N',O}cadmium.

ABSTRACT: 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, ?-? stacking inter-actions [centroid-centroid distance = 3.7455?(19)?Å] contribute to the stabilization of the crystal structure.

Crystal structures of di-bromido-{N-[(pyridin-2-yl-κN)methyl-idene]picolinohydrazide-κ2N',O}cadmium methanol monosolvate and di-iodido{N-[(pyridin-2-yl-κN)methyl-idene]picolinohydrazide-κ2N',O}cadmium.

Project description:The title compounds, [CdBr2(C12H10N4O)]·CH3OH, (I), and [CdI2(C12H10N4O)], (II), are cadmium bromide and cadmium iodide complexes of the ligand (E)-N'-(pyridin-2-yl-methyl-ene)picolinohydrazide. Complex (I) crystallizes as the methanol monosolvate. In both compounds, the Cd2+ cation is ligated by one O atom and two N atoms of the tridentate ligand, and by two bromide anions forming a Br2N2O penta-coordination sphere for (I), and by two iodide anions forming an I2N2O penta-coordination sphere for (II), both with a distorted square-pyramidal geometry. In the crystal of complex (I), mol-ecules are linked by pairs of N-H⋯O and O-H⋯Br hydrogen bonds, involving the solvent mol-ecule, forming dimeric units, which are linked by C-H⋯Br hydrogen bonds forming layers parallel to (101). In the crystal of complex (II), mol-ecules are linked by N-H⋯I hydrogen bonds, forming chains propagating along [010]. In complex (II), measured at room temperature, the two iodide anions are each disordered over two sites; the refined occupancy ratio is 0.75 (2):0.25 (2).

Dichlorido{(2E)-2-[phen-yl(pyridin-2-yl)methyl-idene]hydrazinecarbo-thio-amide}cadmium(II) methanol monosolvate.

Project description:In the title compound, [CdCl2(C13H12N4S)]·CH3OH, the coord-ination geometry of the Cd(II) ion is slightly distorted square-pyramidal, as indicated by the ? 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 hydrazinecarbo-thio-amide moiety adopts an E conformation with respect to the azomethine bond. The solvate mol-ecule in the crystal lattice plays a major role in inter-connecting adjacent mol-ecules by means of O-H?Cl and N-H?O hydrogen-bonding inter-actions. A supra-molecular three-dimensional architecture is sustained in terms of further N-H?Cl and C-H?Cl hydrogen-bonding inter-actions.

Dichlorido{N'-[1-(2-pyridin-2-yl)ethyl-idene]acetohydrazide-?N',O}copper(II).

Project description:In the title compound, [CuCl(2)(C(9)H(11)N(3)O)], the Cu(II) atom is in a distorted square-pyramidal CuCl(2)N(2)O coordination geometry.

In contrast, the Cu-Cl distance from the equatorial chloride ligand is much shorter [2.2110?(7)?Å]. Inter-molecular N-H?Cl and C-H?Cl hydrogen bonds link the complexes into a three-dimensional network.

Project description:The reaction of cadmium acetate dihydrate with 2-acetyl-pyridine (4-phenyl-thio-semicarbazone) yielded the title compound, [Cd(C(14)H(13)N(4)S)(2)].

In the crystal, mol-ecules are connected through inversion centers via pairs of N-H?S inter-actions, building a one-dimensional hydrogen-bonded polymer along [0-1-1].
