Abstract
The solvothermal reaction of [ReOCl3(PPh3)2] with 2,2′-seleno-bis(4,6-di-tert-butylphenol) (H2L1) in ethanol at 95 °C resulted in an oxorhenium(V) complex of formulation [ReO(L1)(L2)] due to the in situ formation of 2-selenochloromethyl-4,6-di-tert-butylphenolate (L2) through the cleavage of one C–Se bond of H2L1. The mononuclear oxorhenium(V) complex was characterized by physicochemical and spectroscopic methods along with detailed structural analysis by single crystal X-ray crystallography. Electrochemical studies revealed a one-electron equivalent quasi-reversible voltammogram for the ReO(V)/ReO(VI) redox couple at 1.28 V (versus SCE) with no cathodic response for ReO(V) → ReO(IV) reduction.
