چکیده
The asymmetric unit of the title compound, {[Pb(C(9)H(6)NO)(2)]·0.5C(3)H(7)NO}(n), comprises Pb(quinolate)(2) and half a dimethyl-formamide mol-ecule (which is disordered about a centre of inversion). The quinolate ligands N,O-chelate to a Pb(II) ion and simultaneously bridge a neighbouring Pb(II) ion to form a polymeric chain along [100] comprising Pb-linked Pb(2)O(2) distorted rhombi. These chains pack to form a square grid, with the channels thus defined occupied by the disordered solvent mol-ecules.

In the title polymeric complex, [Ni(C(2)H(6)NO(3)S)(2)](n), the Ni(II) ion occupies a special position on an inversion centre and displays a slightly distorted octa-hedral coordination geometry, being linked to four sulfonate O atoms and to two N atoms of the taurine ligands. The sulfonate groups doubly bridge symmetry-related Ni(II) centers, forming polymeric chains along the a axis.

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...

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.

In the title structure, [Pb(C(5)H(3)N(2)O(2))(2)](n), the Pb(II) ion is six-coordinated by two pyridazine-3-carboxyl-ate ligands via N and O atoms, with the carboxyl-ato O atoms acting as bidentate and bridging adjacent Pb(II) ions, giving rise to catenated mol-ecular ribbons propagating along the a-axis direction. The ribbons are connected by C-H⋯O hydrogen bonds and van der Waals inter-actions.
