The Creutz-Taube ion, |(NH3)5|2 pyrazine 5+, is studied using the first-principles HFS DVM Xα tecnique. A model based on three sites (two Ru centers and the pyrazine bridge) successfully explains the observed energy levels and the intervalance transfers band. A delocalized (Robin-Day III) ground state seems implied by these results, but definitive characterization awaits full vibronic treatment.
