| Abstract: C5Me4(benzyl)H reacted with Mo(CO)6 in refluxing xylene to give the new complex (C5Me4benzyl)2Mo2(CO)6. Its molecular structure was characterized by elemental analysis, IR spectra, 1H NMR and X-ray diffraction. Crystal data for this compound: Triclinic, space group P1, Mr=782.56, a=0.854 43(17) nm, b=0.991 0(2) nm, c=1.035 5(2) nm, α=67.25(3)°, β=87.38(3)°, γ=85.99(3)°, V=0.806 4(3) nm3, Z=1, Dc=1.611 g·cm3, μ(Mo Kα)=0.825 mm-1, F(000)=398, R=0.032 9, wR=0.083 6 (observed reflections with I>2σ(I)) and R=0.036 2, wR=0.084 3 (all reflections). The X-ray crystal structure of the dimer confirms the structure with terminal CO groups and the Mo-Mo bond distance is 0.326 6 nm. CCDC: 693386. |
