A strategy for the synthesis of heterobi- and heterotrinuclear phosphido-bridged complexes via the reactions of the readily available η6-arene compounds (p-cymene)RuCl2(PPh2X) (X = H, Cl) with Co2(CO)8 is described. This route has afforded heterobinuclear (CO)4Ru(μ-PPh2)Co(CO)3 (3), (p-cymene)(CO)Ru(μ-PPh2)Co(CO)3 (7), small amounts of Ru2(μ-PPh2]2(CO)6 (4), and the heterotrinuclear clusters Ru2Co(μ-PPh2)(CO)10 (5) and RuCo2(μ-PPh2)2(CO)8 (6). These compounds have been characterized by microanalysis and mass, infrared, and NMR (1H, 13C, 31P) spectroscopy. Single crystals of RuCo2(μ-PPh2]2(CO)8 are monoclinic of space group P21/n with a = 12.714 (2) A?, b = 15.600 (3) A?, c = 17.246 (3) A?, β = 108.33 (1)°, and Z = 4. The structure was solved and refined by using 3610 unique, observed reflections measured on a Syntex P21 diffractometer to R and Rw values of 0.034 and 0.039. In the triangular cluster the trans axial PPh2 groups bridge the Ru-Co(1) and Co(1)-Co(2) edges with a semibridging CO group across the remaining Ru-Co bond.
