Poly[bis-{?-N'-[(pyridin-4-yl)methyl-idene]benzohydrazidato}copper(II)].

ABSTRACT: In the title complex, [Cu(C13H10N3O)2] n , the copper(II) cation is located on a crystallographic inversion centre and adopts an elongated octa-hedral coordination geometry with the equatorial plane provided by trans-arranged bis-N,O-chelating acyl-hydrazine groups from two ligands and the apices by the N atoms of two pyridine rings belonging to symmetry-related ligands. The ligand adopts a Z conformation about the C=N double bond. The dihedral angle between the pyridine and phenyl rings is 2.99?(13)°. An intra-ligand C-H?N hydrogen bond is observed. In the crystal, each ligand bridges two adjacent metal ions, forming a (4,4) grid layered structure. ?-? stacking inter-actions [centroid-centroid distances in the range 3.569?(4)-3.584?(9)?Å] involving rings of adjacent layers result in the formation of a three-dimensional supra-molecular network.

Bis{?-2-[bis-(pyridin-2-yl)methyl-idene]hydrazinecarbothio-amidato}bis-[bromido-copper(II)] methanol disolvate.

Project description:In the centrosymmetric binuclear title compound, [Cu(2)Br(2)(C(12)H(10)N(5)S)(2)]·2CH(3)OH, the Cu(II) ion adopts a slightly dis-torted square-pyramidal coordination geometry. The hydrazine carbothio-amide moiety and one of the pyridyl rings together adopt an almost planar arrangement, with a maximum deviation of 0.052?(4)?Å for the C atom of the thio-urea moiety. There are two mol-ecules of methanol solvent per complex in the asymmetric unit. The nonconventional intra-molecular C-H?Br hydrogen bonds make the mol-ecule more rigid, whereas the conventional N-H?N and O-H?Br inter-molecular hydrogen-bonding inter-actions, supported with N-H?? inter-actions, establish a supra-molecular linkage among the mol-ecules in the crystal. An intermolecular C-H?O inter-action is also present.

Bis[N'-(9H-fluoren-9-yl-idene)benzohydrazidato-κN',O]copper(II).

Project description:In the title complex, [Cu(C(20)H(13)N(2)O)(2)], the Cu(II) ion is tetra-coordinated by an N(2)O(2) set of two ligands in a distorted recta-ngular-planar geometry. The dihedral angle between the two coordinated five-membered metalla rings is 37.5 (3)°. The mol-ecular configuration is stabilized by two C-H⋯O and two C-H⋯N intra-molecular hydrogen bonds. The crystal packing is dominated by van der Waals inter-actions. Three atoms of the phenyl ring of the benzohydrazidate moiety are disordered over two sets of sites in a 0.625 (18):0.375 (18) ratio.

Project description:The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.

Project description:The asymmetric unit of the title compound, [Ni(C(15)H(14)N(3)S(2))(2)], consists of two independent mol-ecules with similar configurations. Each Ni(2+) cation is coordinated in a cis-mode by two tridentate N,N',S-chelating Schiff base ligands, creating a distorted octa-hedron [the smallest angle being 77.57?(7)° and the widest being 168.97?(7)° for one mol-ecule, and 78.04?(7) and 167.55?(7)° for the second mol-ecule]. The dihedral angle between the mean coordination planes of the two ligands is 86.76?(7)° for one and 89.99?(7)° for the second mol-ecule. ?-? inter-actions between neighbouring pyridine rings with plane-to-plane distances of 3.540?(1) and 3.704?(1)?Å are observed.

(1-{(E)-[Phen-yl(pyridin-2-yl-?N)methyl-idene]amino-?N}pyrrolidin-2-one-?O)bis-(thio-cyanato-?N)copper(II).

Project description:The Cu(II) atom in the title compound, [Cu(NCS)(2)(C(16)H(15)N(3)O)], is bonded to the N atoms of two thio-cyanate ions, and is N,N'-chelated by the Schiff base ligand. The four N atoms surround the metal atom to form a distorted square; the square environment is distorted towards a square pyramid by a long Cu?O inter-action. In the crystal, two C atoms of the pyrrolidin-2-one ring are disordered over two positions in a 1:1 ratio.

Poly[[{?(3)-dihydrogen [(pyridin-4-yl-methyl-imino)-bis-(methyl-ene)]diphos-phon-ato-?O:O',N,O'':N'}copper(II)] dihydrate].

Project description:In the title polymer, {[Cu(C(8)H(12)N(2)O(6)P(2))]·2H(2)O}(n), the geometry of the five-coordinate Cu(II) ion can best be described as slightly distorted square-pyramidal formed by one N and two O atoms of an N(CH(2)PO(3)H)(2) group and one N atom from a pyridine ring. The elongated apex of the pyramid is occupied by one O atom from a third diphospho-nate ligand. The inter-connection of Cu(2+) ions by the diphospho-nate ligands results in the formation of a double-chain array along the b axis, in which the two sub-chains are inter-locked by pairs of PO(3) groups. The outside of each sub-chain is decorated by other PO(3) groups. These double chains are further assembled into a three-dimensional supra-molecular architecture via a large number of O-H?O hydrogen bonds between the phospho-nate groups and lattice water mol-ecules.

[Aqua-bis-(nitrato-?O)copper(II)]-?-{bis-[5-methyl-3-(pyridin-2-yl)-1H-pyrazol-4-yl]selenide}-[diaqua-(nitrato-?O)copper(II)] nitrate monohydrate.

Project description:In the title binuclear complex, [Cu2(NO3)3(C18H16N6Se)(H2O)3]NO3·H2O, the Cu(II) ions are penta-coordinated in a tetra-gonal-pyramidal geometry. In both cases, the equatorial planes are formed by a chelating pyrazole-pyridine group, a water mol-ecule and a nitrate O atom, whereas the apical positions are occupied by a water mol-ecule for one Cu(II) ion and a nitrate O atom for the other. The organic selenide ligand adopts a trans configuration with respect to the C-Se-C plane. Numerous inter-molecular O-H?O and N-H?O hydrogen bonds between the coordinating and lattice water mol-ecules, nitrate anions and pyrazole groups are observed. ?-? stacking inter-actions between the pyridine rings [averaged centroid-centroid distance = 3.652?(5)?Å] are also present. The lattice water molecule is equally disordered over two sets of sites.

catena-Poly[[bis-(acetato-?O)aqua-copper(II)]-?-5-(pyridin-3-yl)pyrimidine-?N:N].

Project description:In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157?(2)?Å and the Cu(II) ion is displaced by 0.050?(3)?Å from this plane towards the apical water O atom. Bridging through the bis-monodentate 5-(pyridin-3-yl)pyrimidine ligand forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure parallel to (100). The crystal studied was an inversion twin with a 0.57?(3):0.43?(3) domain ratio.
