Abstract
Crystal Structure of the Molybdenum(V) Complex [MoCl3(NtBu)(H2NtBu)]2 · 1/2 C7H8 Green moisture sensitive single crystals of [MoCl3(NtBu)(H2NtBu)]2 (1 · 1/2 C7H8) have been prepared from molybdenum pentachloride with Me2Si(HNtBu)2 in toluene solution; they were suitable for a crystal structure determination. 1 · 1/2 C7H8: Space group P 1, Z = 2, lattice dimensions at –83 °C: a = 696.9(1), b = 1470.9(2), c = 1579.0(2) pm, α = 96.673(13)°, β = 92.014(14)°, γ = 94.852(14)°, R = 0.0321. 1 forms centrosymmetric molecules in which the molybdenum atoms are linked by two μ-Cl-bridges with MoCl bond lengths of 245.7 and 270.2 pm in average of the two crystallographically independent individuals. The longer MoCl bond is in trans-position to the nitrogen atom of the imido ligand (MoN distance 169.0 pm, MoNC bond angle 167.0° in average).
