Abstract

A (Te, S2) ligand, bis(2-methylthioethyl)telluride has been synthesized by reacting Na2Te with ClCH2CH2SMe under a nitrogen atmosphere, as an unstable liquid which is reasonably stabilized on complexation. The complexes of this (Te, S2) ligand having composition [M(PPh3)2(L)](CIO4)2 [L = (Te, S2) ligand] where M = Pd(II), Cd(II) and Hg(II) have been synthesized. 1H and 13C(1H) NMR, IR and FAB mass spectra have been used in conjunction with molecular weight and conductance measurements to characterize the ligand and its complexes. The potentially tridentate ligand coordinates in a bidentate mode and in solution there is an exchange between SMe of the pendent arm and the coordinated SMe group.
