Crystallographic Studies of Lead Coordination Compounds

The changes in the geometry of Pb2+ in several coordination complexes with systematic variations in both the ligand and the counter ions are being investigated to gain insight into the coordination chemistry of Pb2+. These results will be used as the foundation for understanding the molecular basis for the in vivo toxicity of Pb2+. Crystal structures of several simple bidentate, tridentate, tetradentate, and hexadentate ligands with Pb2+ and with NO3-, ClO4- , PF6-, and tetraphenyl borate as counter ions will be presented. The structures of these complexes will be discussed in terms of the stereochemical activity of the lead lone pair and the possible interaction between the Pb2+ and the phenyl rings of tetraphenyl borate.
