Synthesis and characterization of [Mo(μ-EPh)(CO)3(CH3CN)]2 (E = Se, Te), including the X-ray structure of the tellurium derivative
The reaction of Mo(CO)3(MeCN)3 and E2Ph2 (E = Se, Te) yields the edge-sharing bioctahedral, metal-metal bonded Mo(I) products [Mo(CO)3(MeCN)(μ-EPh)]2. The structure of the tellurolato derivative was confirmed by X-ray crystallography: triclinic, space group P1̄, a = 7.3149(17), b = 9.6959(16), c = 9.7090(10) A, α = 80.366(10), β = 76.563(13), γ = 72.877(16)°, V = 636.43(19) A3, D(calc) = 2.222 Mg m-3, μ = 3.271 mm-1, R1 = 0.0418 wR2, = 0.0689 for 163 parameters and 2238 data with I > 2σ(I). The interaction of these compounds with excess E2Ph2 as a possible entry to homoleptic Mo(EPh)3 has been investigated. (C) 2000 Elsevier Science S.A.
