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

Two novel complexes, [Zn(L-1(2-))(L-2)] (1) and [Ni(L-3(2-))(L-4)center dot 2H(2)O] (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 P2(1)/c With a = 9.21400(15), b = 18.1172(3), c = 15.7669(2) angstrom, beta = 91.1769(13)degrees, C30H26N4O4Zn, M-r = 571.92, V= 2631.44(7) angstrom(3), Z = 4, D-c = 1.444 g.cm(-3), mu = 1.659 min(-1), F(000) = 1184, lambda(CuK alpha) = 1.54178 angstrom, the final R = 0.048, wR = 0.1442 and S = 1.139. Compound 2 crystallizes in triclinic, space group P (1) over bar with a = 7.0664(3), b = 9.5265(4), c = 12.8861(6) angstrom, alpha = 74.066(4), beta = 87.408(3), gamma = 83.591(3)degrees, C34H32N6O6S2Ni, M-r = 743.49, V= 828.83(6) angstrom(3), Z = 1, D-c = 1.490 g.cm(-3), mu = 2.490 mm(-1), F(000) = 386, lambda(CuK alpha) = 1.54178 angstrom, the final R = 0.0315, wR = 0.0861 and S = 1.022. Complex 1 is the 1D chain which is linked by C-H center dot center dot center dot 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 center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonding interactions.
