The reaction of a dinuclear tetrahydrido-ruthenium complex (η⁵-C₅Me₅)Ru(μ-H) ₄Ru(η⁵-C₅Me₅) (1) with 2 equiv of diphenylacetylene results in the formation of the dinuclear ruthenium dihydride complex (η⁵-C₅Me₅)Ru(7μ-H) ₂(μ-PhCCPh)Ru(η⁵-C₅Me₅) (2), which contains a perpendicularly bridging diphenylacetylene ligand. The complex crystallizes in the triclinic system, in space group P1, with a = 10.284 (4) A?, b = 15.871 (4) A?, c = 10.286 (3) A?, α = 98.47 (3)°, β = 110.92 (2)°, α = 98.22 (3)°, V = 1515.8 (9) A?³, and Z = 2. Anisotropic refinement of all atoms except hydrogen atoms converged to the residuals R = 0.0569 and R_w = 0.0539 for 6177 reflections.
