Electrochemistry of AuII and AuIII pincer complexes: determination of the AuII–AuII bond energy

Abstract

The bond energy of the unsupported Au–Au bond in the Au(II) dimer [(C^∧N^∧C)Au]₂ and the difference between Au^III–OH and Au^III–H bond enthalpies have been determined experimentally by electrochemical methods, with Au–OH and Au–H complexes showing unexpected differences in their reduction pathways, supported by DFT modelling.
