The crystal, molecular, and electronic structure as well as the electrochemical behavior of o-phenanthroline complexes [M3Se7(o-phen)3]X4 (M = Mo, W; X = Cl, Br) were investigated. Recrystallization of [Mo3Se7(o-phen)3]Br4 from concentrated hydrochloric acid gave crystals corresponding to [Mo3(µ3-Se)(µ2-Se2)3(o-phen)3]Cl4·12H2O, for which X-ray analysis was performed. The bromide is isostructural. Solid-state cyclic voltammetry shows that [M3Se7(o-phen)3]Br4 (M= Mo, W) undergoes reversible three-electron reduction, which is phen-centered with strong delocalization on the metal. DFT calculations for {[Mo3Se7(o-phen)3]Br}3+, [Mo3-Se7(o-phen)3]4+, and {[Mo3Se7(o-phen)3]Br}0 support the correct formulation of the reduction process. Strong interactions between the Cl– or Br– and Se2 ligands of the M3Se7 cluster, observed in the crystal, can be described as donor–acceptor covalent bonding and are important enough to influence the redox behavior of the cluster.
