Abstract The reactions of RuH3[P(C6H5)3] 3 − with Cr(CO)3(CH3CN)3, Mo(CO)3 (diglyme), or W(CO)3(C3H2CN)3 resulted in the formation of the appropriate [(H5C6)3P]3Ru(μ-H)3 M(CO) 3 − complexes, which have been characterized analytically, spectroscopically, and in one case (M = Cr) by an X-ray diffraction study of the K [N(C2H4OC2H4OCH3)3]+ salt. This complex crystallizes in the triclinic space group Pl witha = 13.666(6),b= 13.7901(7),c = 18.147(8) A,a = 93.23(3)°, β = 94.07(4)° γ = 90.43(4)°, andV = 3405.6 A3 for Z = 2. Final discrepancy indices ofR = 0.048 and Rù = 0.056 were obtained. The hydride ligands, all of which could be located and their positional coordinates refined, completed local pseudo-octahedral coordination about both the ruthenium and thechromium centers. The Ru-H bonds are significantly shorter than the Cr-H ones, 1.65(4) vs. 1.92(4) A, and the Ru-Cr bond distance is 2.5474(9) A.
