Di-?-chlorido-bis-(chlorido-{N'-[phen-yl(pyridin-2-yl-?N)methyl-idene]pyridine-2-carbohydrazide-?(2) N',O}cadmium).

ABSTRACT: The title compound, [Cd2Cl4(C18H14N4O)2], was obtained from the reaction of Cd(NO3)2·4H2O with 2-phenyl-pyridine-keton picolinoyl hydrazone and sodium chloride. Each Cd(2+) cation is coordinated by two N atoms and one O atom of the tridentate ligand and three chloride anions, forming a distorted CdNOCl3 octahedron. Each pair of adjacent metal cations is linked by two bridging chloride ligands, resulting in a dinuclear complex unit. The mol-ecular conformation is stabilized by intra-molecular N-H?N and C-H?O hydrogen bonds. In the crystal, mol-ecules are linked by nonclassical C-H?O and C-H?Cl hydrogen bonds into a three-dimensional network. In addition, ?-? stacking inter-actions [centroid-centroid distances = 3.777?(2) and 3.631?(2)?Å] contribute to the stabilization of the crystal packing.

Di-aqua-bis-{?-1,5-bis-[(pyridin-2-yl)methyl-idene]carbonohydrazide(1-)}di-?-chlorido-tetra-chlorido-tetra-zinc(II).

Project description:A tetra-nuclear ZnII complex, [Zn4(C13H11N6O)2Cl6(H2O)2] or {[Zn2(HL)(H2O)(Cl2)](?Cl)2[Zn2(HL)(H2O)(Cl)]}2, was synthesized by mixing an equimolar amount of a methanol solution containing ZnCl2 and a methanol solution containing the ligand H2 L [1,5-bis-(pyridin-2-yl-methyl-ene)carbono-hydrazide]. In the tetra-nuclear complex, each of the two ligand mol-ecules forms a dinuclear unit that is connected to another dinuclear unit by two bridging chloride anions. In each dinuclear unit, one ZnII cation is penta-coordinated in a N2OCl2 in a distorted square-pyramidal geometry, while the other ZnII cation is hexa-coordinated in a N3OCl2 environment with a distorted octa-hedral geometry. The basal plane around the penta-coordinated ZnII cation is formed by one chloride anion, one oxygen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical position occupied by a chloride anion. The basal plane of the hexa-coordinated ZnII cation is formed by one chloride anion, one hydrazinyl nitro-gen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical positions occupied by a water oxygen atom and a bridged chloro anion from another dinuclear unit, leading to a tetra-nuclear complex. A series of intra-molecular C-H?Cl hydrogen bonds is observed in each tetra-nuclear unit. In the crystal, the tetra-nuclear units are connected by inter-molecular C-H?Cl, C-H?O and N-H?O hydrogen bonds, forming a planar two-dimensional structure in the ac plane.

N'-[(E)-(3-Fluoro-pyridin-2-yl)methyl-idene]pyridine-3-carbohydrazide dihydrate.

Project description:The organic molecule in the title dihydrate, C12H9FN4O·2H2O, exists in the E conformation with respect to the azo-methane C=N double bond. The mol-ecule is approximately planar, with a maximum deviation of 0.117?(1)?Å for the carbonyl O atom from the mean plane of the mol-ecule. Both pyridine rings are essentially coplanar with the central C(=O)N2C unit [dihedral angles = 1.99?(7) and 5.71?(8)°], exhibiting a significant difference in dihedral angles from its benzohydrazide analogue. The crystal packing features N-H?O, O-H?N and O-H?O hydrogen-bond inter-actions, which lead to the formation of a chain along the c-axis direction through one of the water mol-ecules present, and these chains are stacked one over the other by means of ?-? inter-actions [with centroid-centroid distances of 3.7099?(10) and 3.6322?(10)?Å] between the aromatic rings in neighbouring anti-parallel mol-ecules, building a three-dimensional supra-molecular network.

N'-[(E)-1-(2-Fluoro-phen-yl)ethyl-idene]pyridine-4-carbohydrazide.

Project description:The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine bond. The pyridyl and fluoro-benzene rings make dihedral angles of 38.58?(6) and 41.61?(5)° respectively with the central C(=O)N2CC unit, resulting in a non-planar mol-ecule. The inter-molecular inter-actions comprise two classical N-H?O and N-H?N hydrogen bonds and four non-classical C-H?O and C-H?F hydrogen bonds. These inter-actions are augmented by a weak ?-? inter-action between the benzene and pyridyl rings of neighbouring mol-ecules, with a centroid-centroid distance of 3.9226?(10)?Å. This leads to a three-dimensional supra-molecular assembly in the crystal system. The F atom is disordered over two sites in a 0.559?(3): 0.441?(3) ratio, through a 180° rotation of the fluoro-benzene ring.

N'-[(1E)-1-(2-Fluoro-phen-yl)ethyl-idene]pyridine-3-carbohydrazide.

Project description:The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine double bond whereas the N and methyl C atoms are in a Z conformation with respect to the same bond. The ketonic O and azomethine N atoms are cis to each other. The non-planar mol-ecule [the dihedral angle between the benzene rings is 7.44?(11)°] exists in an amido form with a C=O bond length of 1.221?(2)?Å. In the crystal, a bifurcated N-H?(O,N) hydrogen bond is formed between the amide H atom and the keto O and imine N atoms of an adjacent mol-ecule, leading to the formation of chains propagating along the b-axis direction. Through a 180° rotation of the fluoro-phenyl ring, the F atom is disordered over two sites with an occupancy ratio of 0.632?(4):0.368?(4).

Project description:In the crystal of the title compound, [Cu(2)Cl(4)(C(50)H(32)N(9)O(8)P(3))(2)], the binuclear mol-ecule is located across an inversion center. Each Cu(2+) cation is coordinated by two pyridine N atoms from symmetry-related 4,4;6,6-bis-(biphenyl-2,2'-diyldi-oxy)-2,2-bis-{2-[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]phen-oxy}cyclo-triphosphazene (L) ligands, a pair of bridging Cl(-) anions and a terminal Cl(-) anion, forming a distorted CuCl(3)N(2) square-pyramidal geometry. Weak intra-molecular C-H?O and inter-molecular C-H?N inter-actions occur in the crystal.

Bis[N-(2-hy-droxy-eth-yl)-N-propyl-dithio-carbamato-?S,S']bis-(4-{[(pyridin-4-yl-methyl-idene)hydrazinyl-idene]meth-yl}pyridine-?N)cadmium.

Project description:The complete mol-ecule of the title compound, [Cd(C(6)H(12)NOS(2))(2)(C(12)H(10)N(4))(2)], is generated by crystallographic inversion symmetry. The distorted octa-hedral trans-N(2)S(4) donor set for the Cd(2+) ion is defined by two symmetrically S,S'-chelating dithio-carbamate anions and two pyridine N atoms derived from two monodentate 4-pyridine-aldazine (or 4-{[(pyridin-4-yl-methyl-idene)hydrazinyl-idene}meth-yl]pyridine) mol-ecules [dihedral angle between the aromatic rings = 17.33?(8)°]. In the crystal, mol-ecules are connected into a supra-molecular chain via O-H?N hydrogen bonds involving the 4-pyridine-aldazine N atoms not involved in coordination to cadmium. Weak C-H?O and C-H?N links consolidate the packing.
