Quantifying effects of second-sphere cationic groups on redox properties of dimolybdenum quadruple bonds

Abstract

A series of four dimolybdenum paddlewheel complexes supported by anionic N,N-dimethylglycinate (DMG) or zwitterionic N,N,N-trimethylglycine (TMG) ligands was synthesised to examine the effects of charged groups in the second coordination sphere on redox properties of Mo[quadruple bond, length as m-dash]Mo bonds. An average shift in reduction potential of +35 mV per cationically charged group was measured, which is approximately half of what would be expected for an analogous mononuclear complex.
