DOIAbstract
The phosphinidene complex [Mo<sub>2</sub>Cp(μ-κ<sup>1</sup>:κ<sup>1</sup>,η<sup>5</sup>-PC<sub>5</sub>H<sub>4</sub>)(CO)<sub>2</sub>(η<sup>6</sup>-HMes*)] reacts with CO to give the diphosphanediyl derivative [Mo<sub>2</sub>{μ-κ<sup>1</sup>,η<sup>5</sup>:κ<sup>1</sup>,η<sup>5</sup>-(C<sub>5</sub>H<sub>4</sub>)PP(C<sub>5</sub>H<sub>4</sub>)}(η<sup>6</sup>-HMes*)<sub>2</sub>]. 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
