Description

Two complexes of Pb(II) with nitrilotris(methylenephosphonic) acid are synthesized and their crystal structures are determined. Nitrilotris(methylenephosphonato)lead(II) [Pb{μ5-NH(CH2PO3H)3}] is a coordination 3D polymer; space group Pī, Z = 2. The coordination polyhedron of Pb is a distorted pentagonal bipyramid with the N atom at one of the equatorial positions. Tetrasodium bis[aquanitrilotris(methylenephosphonatoplumbate( II)] decahydrate Na4[Pb2(H2O)2{μ3-N(CH2PO3)3H2}2] · 10H2O crystallizes in space group Pī, Z = 2. The degree of asymmetry of the coordination polyhedra of lead atoms characterizing the localization of the lone 6s electron pair is estimated.
