Abstract

Square-wave voltammograms of the complex Mo(His-N_ε-C₂H₄CO ₂Me)(η-allyl)(CO)₂ (His = N_δ,N,O-L-histidinate) 2 recorded at variable temperatures establish the existence of two isomers in solution in both the reduced and the oxidized paramagnetic form of 2; a complete analysis yields thermodynamic parameters such as equilibrium constants, ΔG and ΔH for all species.
