Two-dimensional Supramolecular Structure of a Mercury（Ⅱ） Iodide Complex with Organosulfide

摘要

cqvip:A mercury(Ⅱ) iodide complex with organosulfide [Hg(pymt)(pymtH)I] 1 (pymt = the anion of pyrimidine-2-thiolate) has been synthesized by slow evaporation of the solution at room temperature and structurally characterized by single-crystal X-ray diffraction. Basic ideas and data collected are given. X-ray diffraction analysis reveals that complex 1 is mononuclear. Crystallographic data: C8H7HgIN4S2, Mr = 550.79, monoclinic system, space group P21/c, a = 11.218(4), b = 9.551(3), c = 15.877(4) , β = 129.697(15)°, V = 1308.9(7) 3, Z = 4, Mr = 550.79, Dc = 2.795 g/cm3, F(000) = 992, μ(MoKα) = 14.415 mm-1, λ(MoKα) = 0.71073 , T = 293(2) K, 2θmax = 54.9o, GOOF = 1.053, the final R = 0.0310 and wR = 0.0742 for 2547 observed reflections with I > 2σ(I) (refinement on F2). Complex 1 is connected through hydrogen bonds to give a one-dimensional supramolecular chain structure. Furthermore, π-π interactions are also found between the pyrimidine rings with the center-to-center distances of 3.439(4) and 3.603(4) , so complex 1 expands the chains into a two-dimensional network.
