their MII2 oxidation state compared to their [M2(bpbp)(RCO2)2]+ analogues. Manganese complexes are stabilised by approximately 550 mV and cobalt complexes by 650 mV. (ii) The auxiliary bridging carboxylato ligands further attenuate the metal-based redoxchemistry. Substitution of two acetato for two trifluoroacetato ligands shifts redox couples by 300–400 mV. Within the working potential window, reversible

mononuclear complex of V(IV)=O was isolated even in the presence of acetate, possibly because the oxyl groups on each V(IV) prevent formation of a bis-acetato-bridged complex. Reaction of one equivalent of CuCl(2) with bpsmpH led to isolation of two different mononuclear complexes, dependent on the identity of the solvent. The phenol group is coordinated in only one of these complexes. A dinuclear
