Abstract

A novel complex (p-cymene)Ru(S₂C₂B₁₀H₉)(PhCH=CCH₂OCH(Ph)C≡CH)·CH₂Cl₂ based on the ortho-carborane-1,2-dithiolate ligand and 1-phenyl-2-propyn-1-ol has been synthesized successfully and characterized by IR, NMR, MS, elemental analysis and single-crystal X-ray diffraction. The complex crystallizes in monoclinic system, space group P2₁/n with: a = 10.221(4) Å, b = 14.912(6) Å, c = 24.182(10) Å, α = 90.00°, β = 99.096(6)°, γ = 90.00°, C₃₁H₄₀B₁₀Cl₂ORuS₂, M_r = 772.82, V = 3639(3) Å³, D_c = 1.410 g/cm³, Z = 4, F(000) = 1576, μ(MoK_α) = 0.719 mm^–1, R = 0.0600 and wR = 0.1561 for 5463 observed reflections (I > 2σ(I)). Structural analysis shows that there are the coordination of C=C bond, the formation of C–S bod, and metal-induced B–H activation with the formation of Ru–B bond.
