The synthesis and structural characterization of the complex [Ru₂(μ-Cl)(μ-P^tBu₂)(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-P^tBu₂)(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.
