Studies on Cluster-cracking Method for Synthesizing Dithiolate Complexes

Abstract

Abstract: Mononuclear complexes (Bu₄N)₂ [Cd(mnt)₂], (Bu₄N)₂ [M(dmit)₂](M=Cd, Zn) and binuclear complex (Me₄N)₂ [Zn₂(Sph)₂(S₂TTF(SCH₂)₂)₂] were synthesized by cluster-cracking reaction from precursors 2 [M₄(SPh)₁₀] and 4 [S₄M₁₀(SPh) ₁₆](M=Cd, Zn). The net charge on mercapto sulfurs of these dithiolate ligands was calculated by the methods of quantum chemistry PM3 and resulted in the order: mnt ^2->SPh ^->dmit ^2-> [(MeS)₂TTFS₂]^2-≈ [(CH₂S)₂TTFS₂]^2-. Based on these theoretical and experimental results, the relationship between the charge on mercapto sulfurs and the reaction products was discussed.
