摘要：

Three members of the electron transfer series [Cr-III(dithiolene)(3)](z) (z = 1-, 2-, 3-) along with [Mn-IV(dithiolene)(3)](2-) analogues are shown to possess Cr(III) and Mn(IV) ions, respectively, by X-ray absorption spectroscopy (Cr and Mn K-edges). S K-edge spectra show the Cr series to be linked by ligand-based redox processes. All complexes are octahedral with DFT calculations reproducing the molecular structures and spectroscopic parameters such that [Cr(dithiolene)(3)](0) is predicted to be and octahedral with three S,S'-coordinated radical ligands.
