چکیده
The asymmetric unit of the title complex, [Pb(C(8)H(5)O(4))(C(9)H(6)NO)](n), comprises a Pb(II) cation, a quinolin-8-olate anion and a 3-carb-oxy-benzoate anion. The coordination geometry of the Pb(II) atom is defined by one N and six O atoms, as well as a stereochemically active lone pair of electrons, and is based on a Ψ-dodeca-hedron. The quinolin-8-olate is chelating and the 3-carb-oxy-benzoate anion forms bonds to four different Pb(II) atoms. The benzoate end of the 3-carb-oxy-benzoate ligand chelates one Pb(II) atom and simultaneously bridges two Pb(II) atoms on either side, forming a chain along the b axis. The carboxyl end of the 3-carb-oxy-benzoate connects to a neighbouring chain by employing its carbonyl atom to form a bond to a Pb(II) atom and the hydroxyl group to form a hydrogen bond to a quinolin-8-olate O atom. Thereby, a layer is formed in the bc plane.

The non-centrosymmetric polymorph of (quinolin-8-ol-κ2 N,O)(quinolin-8-olato-κ2 N,O)silver(I)
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-ola...

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 Ψ-cube in which one of t...

In the crystal structure of the polymeric title complex, [Cd(C(11)H(10)O(4))(C(10)H(8)N(2))](n), the Cd(II) cation is chelated by one 2,2-bipyridine ligand and two carboxyl groups from two trimethyl-isophthalate (TMIPA) anions, and is further coordinated by one carboxyl-ate O atom from a third TMIPA anion, forming a distorted penta-gonal-bipyramidal geometry. Each TMIPA anion bridges three Cd(I...

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 thes...

Both independent Pb(II) atoms in the title compound, [Pb(2)(C(10)H(8)NO)(2)(C(2)H(3)O(2))(2)], are chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted Ψ-fac octa-hedron in which one of the sites is occupied by a stereochemically active lone pair.
