Syntheses and Structures of Two Complexes Based on Mixing Carboxylate Ligands and Imidazole-containing Ligands

摘要

Two novel complexes, [Zn(L2-1)(L2)](1) and [Ni(L2-3)(L4)·2H2O](2), have been synthesized by solvothermal reactions in different solvents through mixing the carboxylate ligand, imidazole-containing ligand and the metal salt. Compound 1 crystallizes in monoclinic, space group P21/c with a = 9.21400(15), b = 18.1172(3), c = 15.7669(2) ?, β = 91.1769(13)o, C30H26N4O4 Zn, Mr = 571.92, V = 2631.44(7) ?3, Z = 4, Dc = 1.444 g·cm-3, μ = 1.659 mm-1, F(000) = 1184, λ(Cu Kα) = 1.54178 ?, the final R = 0.048, w R = 0.1442 and S = 1.139. Compound 2 crystallizes in triclinic, space group P1 with a = 7.0664(3), b = 9.5265(4), c = 12.8861(6) ?, α = 74.066(4), β = 87.408(3), γ = 83.591(3)o, C34H32N6O6S2 Ni, Mr = 743.49, V = 828.83(6) ?3, Z = 1, Dc = 1.490 g·cm-3, μ = 2.490 mm-1, F(000) = 386, λ(CuK α) = 1.54178 ?, the final R = 0.0315, w R = 0.0861 and S = 1.022. Complex 1 is the 1D chain which is linked by C–H···O hydrogen bonding interactions to form a 2D supramolecular architecture. Meanwhile, complex 2 is a 2D(4,4) network with the ABCABC stacking mode and then generates a 3D supramolecular architecture through C–H···N and O–H···O hydrogen bonding interactions.
