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

ABSTRACT: 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(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.

The non-centrosymmetric polymorph of (quinolin-8-ol-?(2) N,O)(quinolin-8-olato-?(2) N,O)silver(I).

Project description:The title compound, [Ag(C9H6NO)(C9H7NO)], crystallizes as a non-centrosymmetric polymorph. The structure was previously reported by Wu et al. [(2006). Acta Cryst. E62, m281-m282] in the centrosymmetric space group Pbcn. The Ag(I) ion displays a distorted tetra-hedral coordination geometry defined by two N and two O atoms from a neutral quinolin-8-ol ligand (HQ) and a deprotonated quinolin-8-olate anion (Q(-)). The dihedral angle between the two ligands is 47.0?(1)°. Strong O-H?O hydrogen bonds link the mol-ecules into a supra-molecular chain along the a-axis direction.

Dichlorido[1-(2,6-dimethyl-phenyl-imino)-1,2-diphenyl-propan-2-ol-?N,O]palladium(II) methanol monosolvate.

Project description:The title compound, [PdCl(2)(C(23)H(23)NO)]·CH(3)OH, was obtained by the reaction of 1-(2,6-dimethyl-phenyl-imino)-1,2-diphenyl-propan-2-ol and palladium chloride in methanol. The Pd atom is four-coordinated by the O atom of a tertiary alcohol, the imine N atom of the hy-droxy-limine part of the bidentate ligand and by two chloride ions, forming a nearly square-planar geometry. The complex mol-ecule and the uncoordinated methanol mol-ecule are connected via an O-H?O hydrogen bond.

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.
