Abstract
Abstract Reaction of Sb(SBut)3 with W(CO)6 in THF gives (CO)5W(μ-SBut)Sb(SBut)2. (1). The structure of (1) was been determined by single crystal X-ray diffraction methods. Crystal data for (1): C17H27O5S3SbW. M = 713.2, monoclinic, space group P21/n (No. 1014), a = 9.892(2), b = 17.489(4), c = 15.014(3) A, Z = 4, U = 2597.1 (5) A3, Dc = 1.824 g cm−3, λ(MoKα) = 0.71073 A. graphite monochromator, μ = 58.22 cm−1. Methods: Multan, difference Fourier, full-matrix least-squares. Refinement of 3083 reflections (I > 3σ(I)) out of 4732 unique observed reflections (2° < 2° < 50°) gives current R and Rw values of 0.043 and 0.047, respectively. All nonhydrogen atoms were refined with anisotropic thermal parameters; hydrogen atoms were not located Data/parameter ratio = 12.6, shift to error ratio = 0.39, highest peak in final difference Fourier = 0.66 eA−3. Data were collected on an Enraf-Nonius CAD-4 diffractometer at 23 ± 2°C. The Sb(SBut)3 ligand binds to W via S giving the W atom an octahedral coordination geometr...
