Syntheses and reactivity of cofacial, dimeric metal–metal bonded ruthenium(II) mixed valence ruthenium(II/III), and ruthenium(III) complexes of [C22H22N4]2–, a dibenzo-tetra-aza[14]annulene ligand
Abstract
A novel series of metal–metal bonded RuII, mixed valence RuII/III, and RuIII complexes [Ru(C22H22N4)]2n+, of a dibenzotetra-aza[14]annulene ligand have been isolated and characterized which possess ground spin-triplet, spin-doublet, and singlet states, respectively.
