Abstract

Phenylsulfoxyacetic acid has been investigated as a potential ambident ligand. The following inorganic derivatives have been synthesized: bidentate chelated platinum(II) complexes of the type M(Pt(C₆H₅SOCH₂CO₂)Cl₂) where M = H⁺, K⁺, Cs⁺ ; bidentate chelated cadmium(II) complex (C₆H₅SOCH₂CO₂)₂Cd·2H₂O ; chlorine-bridged platinum(II) complex (Pt(C₆H₅SOCH₂CO₂H)Cl₂)₂ and a series of phenylsulfoxyacetates of general formula (C₆H₅SOCH₂CO₂)nM·xH₂O where M = Mg(II) , Ca(II), Ba(II), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Ag(I) and Hg(I), n = 1 or 2 and x = 0, 1, 2, or 3/2. -- Analytical data and several spectroscopic techniques have been used to help understand the chemistry of these compounds and to confirm proposed structures. In all of the platinum(II) complexes, the sulfoxy group utilizes sulfur in bonding, while the cadmium(II) complex is O-bonded. In the series of phenylsulfoxyacetates studied here, the sulfoxy group remains uncoordinated.
