Reaction of white phosphorus with [(triphos)Re(CO) 2 (OTf)] ( 1 ) in dichloromethane affords the new tetraphosphorus complex [(triphos)Re(CO) 2 (η 1 ‐P 4 )](OTf) ( 2 ) [triphos = MeC(CH 2 PPh 2 ) 3 ; OTf = OSO 2 CF 3 ]. Compound 2 reacts with a second equivalent of 1 to give the binuclear complex [{(triphos)Re(CO) 2 } 2 (μ,η 1 ,η 1 ‐P 4 )](OTf) 2 ( 3 ) in which a tetrahedro ‐P 4 ligand behaves as tethering unit between two [(triphos)Re(CO) 2 ] + moieties. Complexes 2 and 3 represent the first soluble metal complexes of the tetraphosphorus molecule where the P 4 ligand has not undergone any major modification.
