Abstract

The first oxidation of a species derived from a compound having two linked, quadruply-bonded Mo2 units has been performed and [[cis-Mo2(DAniF)2]2(μ-Cl)4]PF6, 2, has been isolated and characterized in many ways; it has one unpaired electron and a fully delocalized structure where the Mo–Mo distances increase from 2.1191(4) Å in the reduced species to 2.1453(3) Å in 2 and the Kc of 1.3 × 109 is three orders of magnitude larger than that of the Creutz–Taube ion.
