Dinitrogen cobaltates [(Me3P)3CoN2]2Mg(THF)4 and KN2Co(PMe3)3 react with CoCl(PMe3)3 or NiCl2(PMe3)2 to give a novel binuclear complex (Me3P)2Co(CH2PMe2)(PMe2)Co(PMe3)2 of unusual properties. Carbon monoxide produces Me3P(CO)2Co(CH2PMe2)(PMe2)Co(CO)2PMe3 but does not insert into the Co-C bond. A cleavage reaction by trimethylphosphite yields (Me3P)2[(MeO)3P]2CoP(O)(OMe)2. The molecular structure of the title compound reveals a novel heterocyclic system Co2P2C containing a CH2 group bent out of the Co2P2 plane (d(Co = Co) = 242.8(2) pm). The bond distances (d(P = C) = 171 pm, d(Co-C) = 209 pm) and angles (PCCo) = 88° suggest a type of bonding which is best described as a P-metallated phosphorane coordinated to the second Co atom via its ylide function.
