Density functional theory has been used to investigate the effect of high-spin/low-spin crossover on the delocalization of metal-based electrons in homo- and hetero-bimetallic d5d5 face-shared M2Cl93- (M = Fe, Ru, Os) dimers. The energetic contributions of the ligand-field, ΔELF, spin-polarization, ΔEspe, and orbital overlap, ΔEovlp, terms to the high-spin/low-spin and localized/delocalized equilibria in these dimer systems have been quantified. The two equilibria are found to exhibit a strong...[Show more]
