| Abstract: The complex (C5Me4iBu)2Ru2(CO)4 has been synthesized by the reaction of C5Me4iBuH with Ru3(CO)12 in refluxing xylene and its molecular structure was characterized by elemental analysis, IR spectra, 1H NMR and X-ray crystal structure determination. Crystal data for this compound: Triclinic, space group P1, Mr=668.78, a=0.865 96(17) nm, b=0.892 90(18) nm, c=0.975 7(2) nm, α=88.39(3)°, β=71.64(3)°, γ=84.99(3)°, V=0.713 3(2) nm3, Z=1, Dc=1.557 g·cm-3, μ(Mo Kα)=1.091 mm-1, F(000)=342, R1=0.025 3, wR2=0.067 6 (observed reflections with I>2σ(I)) and R1=0.026 9, wR2=0.068 2(all reflections). The structure of the dimer confirms the structure with bridging and terminal CO groups, and the Ru-Ru bond distance is 0.275 19(8) nm. CCDC: 693389. |
