Abstract

Stabilisation of the mixed-valence state in [Mo2(TiPB)3(HDOP)]2 + (HTiPB = 2,4,6-triisopropylbenzoic acid, H2DOP = 3,6-dihydroxypyridazine) by electron transfer (ET) is related to the proton coordinate of the bridging ligands. Spectroelectrochemical studies suggest that ET is slower than 109 s-1. The mechanism has been probed using DFT calculations, which show that proton transfer induces a larger dipole in the molecule resulting in ET. © 2015 The Royal Society of Chemistry.
