Dichlorido{N'-[phen-yl(pyridin-2-yl-?N)methyl-idene]isonicotinohydrazide-?(2)N',O}zinc.

ABSTRACT: The title compound, [ZnCl(2)(C(18)H(14)N(4)O)], crystallizes with two mol-ecules in the asymmetric unit, which differ in the tautomeric (neutral and zwitterionic) forms of the coordin-ating organic ligand. In both mol-ecules, the Zn(II) atom adopts a distorted square-pyramidal geometry by two N and one O atoms of the Schiff base ligand and two Cl atoms acting as monodentate chloride anions. The crystal packing is stabilized by N-H?N and N-H?Cl hydrogen bonds, forming a two-dimensional network parallel to the ac plane.

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.

Project description:In the title compound, [PdCl2(C13H14N2S)], the Pd(II) ion is coordinated by two N atoms of the chelating bidentate ligand and two chloride anions, giving rise to a distorted square-planar geometry. The methyl-substituted thio-phene arm and the pyridine ring are connected to the metal cation through N atoms to form a six-membered chelate ring with a boat conformation, making the complex stable.

(4-{[(Pyridin-4-yl)methyl-idene]amino}-phen-yl)ferrocene.

Project description:The asymetric unit of the title compound, [Fe(C5H5)(C17H13N2)], contains two independent mol-ecules whose conformations differ, especially in the 4-{(pyridin-4-yl)methyl-idene]amino}-phenyl unit where one is flipped by almost 180°. The cyclo-penta-dienyl rings of the ferrocene unit also exhibit different staggered conformations: in one mol-ecule the conformation is staggered by 9.43?(2)° and in the other by 24.46?(1)° from an ideal eclipsed geometry. The plane of the benzene ring is tilted away from the ferrocene group in both mol-ecules, with dihedral angles of 6.97?(1) and 10.30?(2)°. The benzene ring is also slightly twisted from the plane of the pyridine ring, with dihedral angles of 5.98?(2) and 6.51?(2)° in the two mol-ecules.

Dichlorido(1-{(E)-[phen-yl(pyridin-2-yl-?N)methyl-idene]amino-?N}pyrrolidin-2-one-?O)copper(II) monohydrate.

Project description:The Cu(II) atom in the title compound, [CuCl(2)(C(16)H(15)N(3)O)]·H(2)O, is N,N',O-chelated by the neutral Schiff base ligand and exists in a square-pyramidal geometry. It is displaced by 0.316?(1)?Å out of the square plane (r.m.s. deviation = 0.015?Å) in the direction of the apical Cl atom. The apical Cl atoms of adjacent complex units are hydrogen-bond acceptors to two water mol-ecules, the inter-action generating a centrosymmetric dimer through a cyclic R(4) (2)(8) association.
