Ligand-Induced P2 Coupling to an Acyclic P4 LigandThe further terminal coordination of M(CO)5 (M = Cr, Mo W) to [(Cp‴Co)2(μ-η2:2-P2)2] (1), Cp‴ = 1,2,4-tBu3C5H2, affords the polynuclear cobalt complexes [(Cp‴Co)2(μ3(4)-η4:4:1:(1)-P4){M(CO)5}n], n = 1; M = Cr (2a), Mo (2b), W (2c) and n = 2, M = W (3). The X-ray crystal structure analyses as well as low-temperature 31P-NMR studies show that in 1 the two P2 ligands are rectangularly oriented while in 2b, 2c, and 3 they are coupled to an acyclic, trapezoidally arranged P4 chain.
