One Electron Changes Everything: Synthesis, Characterization, and Reactivity Studies of [Re(NCCH₃)₆]³.

ABSTRACT: Oxidation of [Re(NCCH₃)₆]²⁺ with the thianthrene radical cation results in the formation of [Re(NCCH₃)₆]³⁺, one of the very rare cases of a fully solvated +3 complex. It was fully characterized by spectroscopy and X-ray structure analysis. In contrast to its reduced analogue, [Re(NCCH₃)₆]³⁺ exhibits a much faster CH₃CN exchange. Hence, substitution reactions proceed at 20 °C within minutes. Its potential as a versatile precursor for Re^III chemistry was examined with a series of substitution reactions. The more lipophilic analogue [Re(NCPh)₆]³⁺ was synthesized by nitrile exchange in benzonitrile (NCPh). The Re(II) analogue of [Re(NCPh)₆]
