Abstract
A new complex [Pb(HL)(bipy)0.5] (HL = N-[(3-carboxyphenyl)-sulfonyl]glycine dianion, bipy = 4,4′ -bipyridine) has been synthesized from the reaction of N-[(3-carboxyphenyl)-sulfonyl] -glycine with Pb(CH3COO)2· 3H2O in the presence of bipy at 70°C and structurally characterized by single-crystal X-ray diffraction. The complex crystallizes in triclinic, space group P-1 with a = 4.9448(4) Å, b = 11.5868(9) Å, c = 14.1272(11) Å, α = 78.7020(10)°, β = 80.1500(10)°, γ = 83.3080(10)°, the final R = 0.0195 and wR = 0.0491. X-ray analysis reveals that the crystal structure is constructed by mixed ligands. HL 2 − acts as bridging ligand to link two adjacent metal ions to form a one-dimensional chain. These chains are further cross-linked by bridging bipy ligands along the c axis to generate a 2D layer. Lead(II) ions are six-coordinated with a distorted octahedral environment geometry.
