[Elektronische Daten] [David Ellis, Louis Farrugia] The reaction ofRu3(μ-H)(μ-C,N-C5H4N)(CO)10 (1) with Pt(P i Pr3)(nb)2 {nb = bicyclo-[2.2.1]hept-2-ene} does not afford any Ru-Pt mixed metal clusters, but gives instead the mono-substituted phosphine derivative Ru3(μ-H) (μ-C,N-C5H4N)(CO)9(P i Pr3) (2) as the sole isolable product. Single crystal X-ray studies have been carriedout on 1 and 2. Crystal data for 1: monoclinic, space group P21/c,a = 16.9637(10) A,b = 7.6632(5) Á,c = 17.4058(11) Á, β = 117.214(5)°,V = 2009.0(2) Á3,R(R w) = 0.022 (0.034) for 3090 independent absorption corrected data. Crystal data for 2: triclinic, space group PĪ,a = 9.3389(5) Á,b = 11.4376(6) Á,c = 15.1781(8) Á,α = 76.454(4),β = 79.900(5),γ = 67.428(5)°,V = 1448.8(2) Á3 R(R w ) = 0.024 (0.034) for 4564 independent absorption corrected data. In cluster 1 the Ru-Ru bonds are in the range 2.8462(4)-2.8986(4) Á. The hydride andσ-pyridyl ligand bridge the same Ru-Ru vector, and the Ru(μ-H) bridge is symmetric, with Ru-H = 1.78(4) and 1.77(4) Á. In cluster 2 the Ru-Ru distances show a greater ranger 2.7267(3)-3.0604(3) Á. The phosphine ligand is bonded to the Ru atom which is not involved in theσ-pyridyl bridge. In contrast to 1, the hydride andσ-pyridyl ligands in 2 bridge different Ru-Ru vectors and the resultant Ru(μ-H)Ru bridge is asymmetric, with Ru-H = 1.70(4) and 1.89(4) Á.
