The synthesis and structural characterization of the complex [Ru2(μ-Cl)(μ-PtBu2)(μ-dppa)(CO)4] (4, dppa = Ph2PN(H)PPh2) are reported. The title compound and two other related complexes were obtained in high yields by the reaction of the coordinatively unsaturated species [Ru2(μ-H)(μ-PtBu2)(μ-P ̂P) (CO)4] (P ̂P = dppa, 3; P ̂P = Ph2PN(Ph)PPh2,
5; P ̂P = Ph2PN(CH2Ph)PPh2, 6) with carbon tetrachloride. Single crystals of 4 grown from dichloromethane-acetone have been analyzed by X-ray crystallography.
