Study on metal multi-sulfur 1,2-dithiolene coordination compounds of C[Ni(dmid)(2)]

A new series of coordination compounds C[Ni(dmid)(2)] (where C is outer cat ions, H(2)dmid = 1,3-dithiole-2-one-4,5-dithiolate) have been prepared for the first time. The same compound [Ni(dmid)(2)] is obtained when these comp ounds of C[Ni(dmid)(2)] are oxidized. The components of these new compounds have been determined. IR, UV, ESR, XPS, cyclic voltammograms and conductiv ities at room temperature were studied. The XPS spectra show that the elect ron transfer occurs mainly on the ligand during the oxidation. Thus,charge distribution of the ligand changed accordingly.
