Abstract

We report the first synthesis and isolation of the gold dithiolene complex (Bu₄N)[Au(pdt = 2,3-pyrazinedithiol)₂]. We characterize this complex using X-ray crystallography, infrared spectroscopy, cyclic voltammetry, and UV-Vis spectroscopy. The title complex is structurally similar to other gold dithiolene complexes. We find that the monoanion and dianion are linked by a reversible electrochemical event, but electrochemical generation of other redox states are irreversible processes. Generation of the dianion and protonation of the monoanion lead to reversible changes in the UV-Vis spectroscopy - primarily for the HOMO-1 → LUMO transition.
