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.

{1-[1-(2-Hy-droxy-phen-yl)ethyl-idene]-2-(pyridin-2-yl-?N)hydrazine-?2N',O}{1-[1-(2-oxidophen-yl)ethyl-idene]-2-(pyridin-2-yl-?N)hydrazine-?2N',O}nickelate(II) nitrate hemihydrate.

Project description:The 2-hydrazino-pyridine precursor has been widely used to prepare ligands of various kinds by condensation with carbonyl compounds. These types of ligands are suitable for synthesizing novel transition metal (II) complexes with inter-esting magnetic properties. In this context we have synthesized the ligand 1-(2-hy-droxy-phenyl-2-ethyl-idene)-2-(pyridin-2-yl)hydrazine (HL) which was used in the preparation of the mononuclear title complex, [Ni(C13H12N3O)(C13H13N3O)]NO3·0.5H2O. As a result of the presence of HL and L in the [{Ni(HL)(L)}]+ unit, the complex appears to be a supramolecular dimer composed of the ?(-) and ?(-) optical isomers, which are linked by strong hydrogen-bonds. As well as the dimer generated by two mononuclear [{Ni(HL)(L)}]+ cations, the asymmetric unit also contains two nitrate anions and one water mol-ecule. Each Ni atom is coordinated to two ligand mol-ecules by a nitro-gen atom of the pyridine ring, an imine nitro-gen atom and a phenolic oxygen atom of one of the ligand mol-ecules and a phenolate oxygen atom of the other organic mol-ecules. The environment around the cation is a distorted octa-hedron. The basal planes are defined by the two nitro-gen atoms of the pyridine rings and the two phenolic oxygen atoms of the ligand, the apical positions being occupied by the azomethine atoms. The O atoms of one of the nitrate ions are disordered over two sets of sites in a 0.745?(9):0.255?(9) ratio. In the crystal, the dimers are linked by numerous hydrogen bonds, forming a three-dimensional framework.

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. The tridentate acetohydrazide ligand chelates in a meridional fashion. The chloride ligand in the axial position forms a long Cu-Cl distance of 2.4892?(9)?Å. 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.

Bis{4-phenyl-1-[1-(pyridin-2-yl-?N)ethyl-idene]thio-semicarbazidato-?(2)N(1),S}cadmium.

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].

Project description:In the title compound, [Cd(NCS)(2)(C(11)H(17)N(3))](n), the Cd(II) atom is octa-hedrally coordinated by the N,N',N''-tridentate Schiff base ligand and one terminal thio-cyanate N atom. Two trans-N:S-bridging thio-cyanates complete the N(5)S donor set around the Cd atom.
