Bis(?-2-methyl-quinolin-8-olato)-?N,O:O;?O:N,O-bis-[(acetato-?O)(methanol-?O)zinc(II)].

ABSTRACT: The reaction of zinc acetate and 2-methyl-8-hydroxy-quinoline in methanol yielded the centrosymmetric dinuclear title compound, [Zn(2)(C(10)H(8)NO)(2)(CH(3)CO(2))(2)(CH(3)OH)(2)], which has the Zn atom within a distorted NO(4) trigonal-bipyramidal coordination geometry. Methanol-acetate O-H?O hydrogen bonds link the dinculear units into a linear supra-molecular chain extending parallel to [100].

Bis(acetato-?O)bis-(?(3)-quinolin-8-olato-?N,O:O:O)tetra-kis(?(2)-quinolin-8-olato-?N,O:O)tetra-zinc(II) dihydrate.

Project description:In the centrosymmetric title compound, [Zn(4)(C(9)H(6)NO)(6)(C(2)H(3)O(2))(2)]·2H(2)O, the Zn(II) atom that is bonded to one O atom of the acetate group is chelated by a quinolin-8-olate anion. This Zn atom is also bonded to the oxide O atoms of two other quinolin-8-olate anions, which themselves engage in chelation to the other Zn(II) atoms. The Zn(II) atom is five-coordinate in a square-pyramidal coordination geometry. The second Zn(II) atom is six-coordinate as it is linked to two oxide O atoms of the anions that chelate to the acetate-bound metal atom, and is chelated by two quinolin-8-olate ligands. The uncoordinated water mol-ecule is disordered over two positions in a 4:1 ratio. O-H?O hydrogen bonds between the water molecules and the free O atoms of the carboxylate groups consolidate the crystal packing.

(Amino-acetato-?O,N)bis-(quinolin-8-olato-?O,N)cobalt(III) methanol solvate.

Project description:In the crystal structure of the title compound, [Co(C(2)H(4)NO(2))(C(9)H(6)NO)(2)]·CH(3)OH, the Co(III) atom is chelated by two quinolin-8-olate and one glycinate anions in a distorted octa-hedral coordination geometry. The five-membered chelating glycinate ring assumes an envelope conformation. The complex mol-ecules are assembled by inter-molecular N-H?O hydrogen bonding.

Bromido(quinolin-8-ol-?N,O)(quinolin-8-olato-?N,O)zinc(II) methanol monosolvate.

Project description:The title compound, [ZnBr(C(9)H(6)NO)(C(9)H(7)NO)]·CH(3)OH, has its metal atom N,O-chelated by a neutral and a deproton-ated 8-hy-droxy-quinoline ligand. The hy-droxy unit of the neutral ligand is a hydrogen-bond donor to the methanol O atom and the alk-oxy O atom of the monoanionic ligand is a hydrogen-bond acceptor to the methanol O atom. In the crystal, adjacent mol-ecules are linked by these two hydrogen bonds, generating a chain running along the a axis.

Bis(2-methyl-quinolin-8-olato-?N,O)-lead(II).

Project description:The Pb(II) atom in the title compound, [Pb(C(10)H(8)NO)(2)], is chelated by two oxine (2-methyl-quinolin-8-olate) anions in a ?-trigonal-bipyramidal geometry; the N atoms occupy the axial sites. The mol-ecule lies about a twofold rotation axis.

Bis(?-2-methyl-quinolin-8-olato)-?N,O:O;?O:N,O-bis-[(methanol-?O)(nitrato-?O,O')lead(II)].

Project description:The mol-ecule of the title compound, [Pb(2)(C(10)H(8)NO)(2)(NO(3))(2)(CH(3)OH)(2)], lies about a centre of inversion. The Pb atom is chelated by nitrate and substituted quinolin-8-olate anions. The O atom of the quinolin-8-olate also bridges, to confer a six-coordinate status on the metal centre. When a longer Pb?O inter-action is considered, the geometry approximates a ?-cube in which one of the sites is occupied by a stereochemically active lone pair.

Project description:The anion of the title salt, (C(10)H(10)NO)[ZnBr(2)(C(10)H(8)NO)]·CH(3)OH, has its metal atom N,O-chelated by the deprotonated 2-methyl-8-hy-droxy-quinoline ligand. The hy-droxy unit of the cation is a hydrogen-bond donor to the alkoxide O atom of the tetra-hedrally coordinated anion, whereas the ammonium cation is a hydrogen-bond donor to the methano-lic O atom. In the crystal, adjacent ion pairs and solvent mol-ecules are linked by a methanol-halogen O-H?Br hydrogen bond, generating a chain running along the a axis.

Project description:The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinuclear structure is further stabilized by intra-molecular N-H?O(nitrate) hydrogen bonds.
