catena-Poly[[lead(II)-bis(μ2-quinolin-8-olato)-κ3N,O:O;κ3O:N,O] N,N-dimethylformamide hemisolvate]

Abstract

The asymmetric unit of the title compound, {[Pb(C9H6NO)2]·0.5C3H7NO}n, comprises Pb(quinolate)2 and half a dimethylformamide molecule (which is disordered about a centre of inversion). The quinolate ligands N,O-chelate to a PbII ion and simultaneously bridge a neighbouring PbII ion to form a polymeric chain along [100] comprising Pb-linked Pb2O2 distorted rhombi. These chains pack to form a square grid, with the channels thus defined occupied by the disordered solvent molecules.
