Abstract : Four series of metal phosphinate complexes based on the phosphinic acids, (C6H5)2P(O)OH, C6H5(H)P(O)OH, (C6H5)2P(S)OH, and (C6H5)2P(S)SH were synthesized and characterized. Although the primary interest was in the complexes of aluminum(III), nickel(II) and cadmium(II), several other metal complexes were synthesized for comparison purposes. Structural features are discussed, relating the formation of chelated monomer or ligand bridged polymer to the size of the metal cation and to the sulfur or oxygen moieties of the ligands. Hydrolytic stabilities were successfully correlated to the 'hard-soft' concept of acid-base theory. The predicted general relationship seems to exist between the thermal stability and the ionic character of the metal to ligand bonding. (Author)
