摘要：
The title compounds have been obtained by dimerization of MoX2(dppe)(THF) following THF loss in non-coordinating solvents. The chloride compound has been crystallographically characterized as Mo2Cl6(dppe)2.4CH2Cl2: monoclinic, space group P2(1)/n, a = 13.846(1), b = 18.204(2), c = 15.479(1) angstrom, beta = 108.589(7)-degrees, V = 3698(1) angstrom 3, Z = 2, D(c) = 1.38 g cm-3, mu(Cu-K-alpha) = 86.21 cm-1, R = 0.073, R(w) = 0.104 for 365 parameters and 4804 unique data, of which 2823 were observed [F(o)2 > 3-sigma(F(o)2)]. The compound has an edge-sharing bioctahedral configuration and the two metals are separated at a distance of 2.767(2) angstrom.
