摘要：

An electrochemical study of M(dtc) 2 complexes, M = Pd, Pt, established that these complexes can be reduced to the unstable M(dtc) − 2 species and irreversibly oxidized to the tris complexes, M(dtc) + 3, although in low yields. A detailed study of the redox behaviour of the platinum tris compound, Pt(dtc) + 3, revealed that a two electron transfer process occurred, with a very rapid decomposition of the reduced species, according to Pt(dtc) + 3 → Pt(dtc) − 3 → Pt(dtc) 2 + dtc − The electrochemical behaviour of the diseleno complexes, M(dsc) 2 and electrochemically generated M(dsc) + 3, M = Ni, Pd, Pt, closely parallels that of their dtc congeners.
