A new lead(II) inorganic-organic hybrid of the P,P'-diphenylmethylene-diphosphinate ligand: synthesis and X-ray characterization of the [Pb(CH2(P(Ph)O2)2)] complex

By reaction of lead(II) nitrate with P,P'-diphenylmethylenediphosphinic acid in water solution a new inorganic-organic hybrid of formula [Pb(CH2(P(Ph)O2)2)] has been synthesized and structurally characterized. The complex displays a polymeric columnar structure, the column being formed by two intersecting sinusoidal ribbons of lead(II) ions bridged by bifunctional phosphinate ligands. The intersections of the ribbons are constituted by dimeric units of pentacoordinated lead(II) ions.
