Bis(?(2)-pyridine-2-carboxamide oximato)bis-[(pyridine-2-carboxamide oxime)zinc] dinitrate.

ABSTRACT: In the title dinuclear compound, [Zn(2)(C(6)H(6)N(3)O)(2)(C(6)H(7)N(3)O)(2)](NO(3))(2), the Zn(II) cation is N,N'-chelated by one pyridine-2-carboxamide oximate anion and one pyridine-2-carboxamide oxime mol-ecule, and is further bridged by an oxime O atom from the adjacent pyridine-2-carboxamide oximate anion, forming a distorted trigonal bipyramidal coordination. Two pyridine-2-carboxamide oximate anions bridge two Zn(II) cations to form the centrosymmetric dinuclear mol-ecule. Extensive O-H?O, N-H?O and O-H?N hydrogen bonds are present in the crystal structure.

Project description:In the title compound, [Cu(C(6)H(5)N(2)O)Cl(C(6)H(6)N(2)O)], the Cu atom is coordinated by one neutral and one deprotonated pyridine-2-carboxaldehyde oxime (pco) ligand, resulting in the formation of two five-membered CuN(2)C(2) rings. Together with the additional coordinating chloride anion, the coordination polyhedron of copper is best described as a distorted square-pyramid, the distortion parameter being 0.288. The two organic ligands are linked by an intramolecular O-H?O hydrogen bond.

Project description:The asymmetric unit of the title compound, [Zn(C(7)H(8)N(4)S)(2)](NO(3))(2)·2H(2)O, contains two Zn(pht)(2) cations (pht is pyridine-2-carbaldehyde thio-semicarbazone), four nitrate anions and four water mol-ecules.

Crystal structure of bis-(acetato-?O)bis-(pyridine-2-carboxamide oxime-?(2) N,N')cadmium ethanol disolvate.

Project description:In the title compound, [Cd(CH3COO)2(C6H7N3O)2]·2C2H5OH, the Cd(II) atom, which lies on a twofold rotation axis, is coordinated by two monodentate acetate groups and two N,N'-chelating pyridine-2-carboxamide oxime ligands, leading to a distorted octahedral coordination sphere. The mononuclear complex mol-ecules are assembled into chains along the c-axis direction via N-H?O hydrogen-bonding inter-actions. These chains are further assembled by O-H?O hydrogen bonds involving the ethanol solvent mol-ecules into a three-dimensional supramolecular structure.

Project description:In the title compound, C(20)H(18)N(4)O(2), the dihedral angles between the central benzene ring and the pyridine rings are 57.55 (6) and 22.05 (8)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N inter-actions and in the crystal structure an inter-molecular asymmetric cyclic hydrogen-bonding association involving both amide N-H donors and a common amide O-atom acceptor gives a chain extending along the c axis.

A second monoclinic polymorph of (pyridine-2-carboxaldehyde oximato-?N,N')(pyridine-2-carboxaldehyde oxime-?N,N')palladium(II) chloride.

Project description:The asymmetric unit of the title compound, [Pd(C(6)H(5)N(2)O)(C(6)H(6)N(2)O)]Cl, contains one half of a cationic Pd(II) complex and a Cl(-) anion, with a crystallographic mirror plane parallel to the ac plane passing through the Pd and Cl atoms. In the complex, the Pd(II) ion is four-coordinated in a distorted square-planar environment by four N atoms derived from the two chelating ligands. The hy-droxy H atom lies on the mirror plane and so is equidistant from the O atoms. This indicates that the negative charge is delocalized over the two O atoms. The complex mol-ecules are stacked in columns along the c axis and are connected by C-H?O hydrogen bonds, forming a three-dimensional network. The structure reported herein represents a new monoclinic polymorph of the previously reported monoclinic (C2/c) form [Torabi et al. (2007 ?). Z. Kristallogr. New Cryst. Struct. 222, 197-198].

The two unique Ni(II) cations are N,N',N'',O-chelated by carbox-imid-amid-ate(2-) and carboximidamidate(1-) anions, forming a distorted four-coordinate planar structure, while the other two Ni(II) atoms are N,N',O,O'-chelated by the same bridging ligands and two pyridine mol-ecules, affording six-coordinated metals in an octa-hedral geometry. The cation is isostructural with the complex crystallized with perchlorate counter-ions in place of nitrate.
