Abstract
A simple and efficient synthesis of solutions of pure SeCl2 in THF or dioxane (ca. 0.4 M) at 23 °C was achieved by treatment of elemental selenium with an equimolar amount of SO2Cl2. SeCl2 was characterized by 77Se NMR and Raman spectra. SeCl2 forms 1:1 or 1:2 adducts with tetramethylthiourea (tmtu) or tetrahydrothiophene (tht), respectively. The crystal structure of SeCl2·tmtu (1) reveals a T-shaped geometry [d(Se−Cl) = 2.443(4) A] with weak intramolecular Se···Cl interactions [d(Se−Cl) = 3.276(4) A]. Crystals of 1 are triclinic, space group P1, with a = 8.473(3) A, b = 9.236(3) A, c = 7.709(4) A, α = 109.90(3)°, β = 92.26(4)°, γ = 107.89(3)°, V = 532.9(4) A3, and Z = 2. The complex SeCl2(tht)2 (2) adopts a square planar geometry with d(Se−Cl) = 2.4149(8) A. Crystals of 2 are monoclinic, space group C2/c, with a = 15.6784(8) A, b = 9.1678(4) A, c = 9.1246(4) A, β = 110.892(2)°, V = 1225.3(1) A,3 and Z = 4. The reaction of Ph3PS with SeCl2 gives Ph3PCl2 and a complex mixture of selenium sulfides SenS8-n ...
