The crystal structures of 2-XC6H4Pb(OAc)3 (X = CH3, Cl; OAc = OOCCH3) have been determined by X-ray diffraction.Both compounds are isostructural and crystallize as triclinic, space group P<*>.They consist of monomers, the seven-coordinated central atom being in a distorted pentagonal-bipyramidal environment with five O atoms of the three unsymmetrically chelating carboxylate groups in equatorial positions, and one O and one C(aryl) atom in axial positions.IR, 1H, 13C and 207Pb NMR spectroscopic data of these and other monoaryllead triacetates are reported, and similar structures with seven-coordinated lead are inferred.Weak coordination of Y to Pb is discussed to exist possibly in 2-YC6H4Pb(OAc)3 (Y = F, Cl, OCH3).
