The complexes [cation] [Hg(SR)3](R = Me, cation = Et4N+; R = But, cation = Et4N+, Bu4N+, [N(Ph3P)2]+) have been prepared. The crystal structure of the methanethiolate complex shows that it contains centrosymmetric dinuclear anions [(MeS)2Hg(�-SMe)2Hg(SMe)2]2- with distorted tetrahedral geometry about the mercury atoms. Vibrational spectroscopic evidence suggests that this complex dissociates on dissolution in ethanol to give mononuclear [Hg(SMe)3]- species. The ButS- complexes appear to exist as mononuclear [Hg(SBut)3]- species both in the solid state and in solution. The metal-sulfur stretching frequencies are assigned for all of the complexes studied, and the vibrational spectra are discussed in terms of the structures of the complex anions involved.

A study of the low frequency vibrational spectra of the complexes MX2.TMED (where M = Zn, Cd, Hg; X = Cl, Br, I; TMED = N,N,N′,N′-tetramethylethylenediamine suggests that in the solid state the zinc and mercury complexes are 4-coordinated but the cadmium complexes are all based on octahedral halogen bridged structures. Assignments of the vibrational bands are discussed.
