Abstract

125Te NMR data indicate the formation of mixed-ligand species C8H8Te(X)(SS) (X = Cl, Br, I; SS = S2CNEt2, S2P(OR)2, S2COR) in mixtures of C8H8TeX2 and C8H8Te(SS)2. These ligand redistribution reactions are solvent dependent for SS = S2P(OR)2, S2COR. No evidence was found for the existence of the mixed-ligand species C8H8Te(F)(SS). Crystals of [C8H8Te(I)(S2CNEt2)]2 are orthorhombic, space group Pccn with Z = 8, a 13.061(2), b 19.130(2), c 14.043(2). The compound is dimeric through asymmetric iodine bridges; there is evidence of a stereochemically active lone pair which gives an overall seven coordinate 1:2:2:2 geometry about the tellurium atom.
