Abstract

14,15-Bis(hydroxyimino)-13,16-dithiaoctacosane (H-2L) has been prepared from the sodium salt of dodecanethiol and (EE) -dichloroglyoxime. Only mononuclear complexes with a metal-ligand ratio of 1:2 are obtained for Ni(II) or Co(II) with H-2L. Both a mononuclear complex or a polymer can be obtained with Pd(II) depending upon the stoichiometry of the reactants. With Pt(II) only a polymeric product is isolated. For Cu(II), a trinuclear complex is formed in which the metal ions are co-ordinated to both thia and oxime donors. A heteropentanuclear complex and a heteronuclear polymer have been obtained by the reaction of [Ni(HL)2] with silver(I) and palladium(II) salts, respectively. All these complexes are very soluble in common organic solvents; H-1 and C-13 NMR, IR and UV/VIS data are presented,
