Abstract
The electrochemical oxidation of a metallic anode (zinc or cadmium) in an acetonitrile solution of a series of arenephosphinothiol ligands, 2-(Ph(2)P)C(6)H(4)SH, 2-(Ph(2)P)-6-(Me(3)Si)C(6)H(3)SH, 2-(Ph(2)PO)-6-(Me(3)Si)C(6)H(3)SH, and PhP(C(6)H(4)SH-2)(2) [abbreviated RP-(SH)(x)(), x = 1 or 2], affords [M(RP-S)(2)] and [M(RP-S(2))], M = Zn, Cd. Adducts of several of these compounds with 1,10-phenanthroline and 2,2'-bipyridine have also been obtained by addition of these coligands to the electrolysis phase. The compounds obtained have been characterized by microanalysis, IR, UV-visible, FAB spectrometry and (1)H, (31)P NMR spectroscopic studies. The compounds, [Cd(2){2-(Ph(2)PO)C(6)H(4)S}(4)]CH(3)CN (1), [Zn{2-(Ph(2)P)-6-(Me(3)Si)C(6)H(3)S}(2)] (2), [Cd{2-(Ph(2)PO)-6-(Me(3)Si)C(6)H(3)S}(2)(CH(3)OH)] (3), and [Zn{PhPO(C(6)H(4)S-2)(2)}(bipy)] (4), have been also characterized by single-crystal X-ray diffraction. Compound 1 is binuclear with a {Cd(2)S(2)} core and distorted trigonal bipyramidal {CdO(2)S(3)} geometry about the Cd sites. Compounds 2, 3, and 4 are mononuclear with distorted tetrahedral {ZnP(2)S(2)}, distorted square pyramidal {CdO(3)S(2)}, and distorted trigonal bipyramidal {ZnON(2)S(2)} geometries, respectively.
