摘要：

The title compound, [Pb{(SPPh(2))(2)N}(2)], was obtained by reacting potassium tetraphenyldithioimidodiphosphinate with lead(II) acetate. X-ray diffraction analysis reveals an unsymmetrical (anisobidentate) coordination of the chelating ligands, indicated by non-equal Pb-S interatomic distances [2.695(4) and 2.943(4) Angstrom] and some P-N and P-S bond length alternation within the two NP2S2Pb rings that form the spirobicyclic complex. The lead coordination is supplemented by two additional Pb(eta(6)-C6H5) interactions with two phenyl groups. If these interactions are considered, the geometry of the coordination sphere may be described as distorted octahedral.
