Abstract

A new complex [(p-Cymene)Ru(S₂C₂B₁₀H₉)(CH₂CCH(OH)Fc)]₂ · 0.5H₂O (Fc = ferrocenyl) based on the 1,2-dicarba-closo-dodecaborane-1,2-dithiolate ligand and FcCH(OH)C≡CH has been synthesized successfully and characterized by IR, NMR, MS, elemental analysis and single-crystal X-ray diffraction, in which the alkyne is inserted into one of the Ru–S bonds that may further lead to metal-induced B‒H activation, hydrogen atom transfer from the carborane via the metal center to the inserted alkyne, and the generation of a Ru–B bond. The complex crystallizes in triclinic system, space group \(P\bar {1}\) with a = 12.7329(5), b = 13.8422(5), c = 20.0796(7) Å, α = 87.249(3)°, β = 89.311(3)°, γ = 62.961(4)°, C₅₀H₇₃B₂₀O_2.5S₄Fe₂Ru₂, Mr = 1372.37, V = 3148.39(19) ų, ρ_c = 1.448 g/cm³, Z = 1, F(000) = 1394, µ(MoK_α) = 1.094 mm^–1, R = 0.0473 and ωR = 0.0990 for 9294 observed reflections (I > 2σ(I)).
