Chelate complexes of lead(II) with nitrilotris(methylenephosphonic) acid [Pb{μ"5-NH(CH_2PO_3H)_3}] and Na{sub 4}[Pb{sub 2}(H{sub 2}O){sub 2}{μ"3-N(CH_2PO_3)_3H_2}{sub 2}] · 10H{sub 2}O: Synthesis, structure, and asymmetry of lone 6s pair
- Udmurt State University (Russian Federation)
Two complexes of Pb(II) with nitrilotris(methylenephosphonic) acid are synthesized and their crystal structures are determined. Nitrilotris(methylenephosphonato)lead(II) [Pb{μ"5-NH(CH_2PO_3H)_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 Na{sub 4}[Pb{sub 2}(H{sub 2}O){sub 2}{μ"3-N(CH_2PO_3)_3H_2}{sub 2}] · 10H{sub 2}O 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.
