The phosphinidene complex [Mo2Cp­(μ-κ115-PC5H4)­(CO)26-HMes*)] reacts with CO to give the diphosphanediyl derivative [Mo2{μ-κ1515-(C5H4)­PP­(C5H4)}­(η6-HMes*)2]. The latter compound features unreactive lone electron pairs at phosphorus, which instead contribute to the electronic communication between metal centers via a weak π­(PP)-bonding interaction. As a result, this complex displays metal-centered acid–base and redox behavior.
