Syntheses and Crystal Structures of Cd(Ⅱ) and Ni(Ⅱ) Complexes Containing Flexible Sulfide and Nitrogen Heterocyclic Ligands
摘要:
Two new coordination polymers [Cd(EBLA)(ip)(H2O)] (1) and [Ni(EBSA) (im)2(H2O)]n (2) were synthesized by hydrothermal and solution methods using 2,2'-dithiosalicylicacid (EBSA), 1H-imidazo[4,5-f][1,10]phenanthroline (ip), imidazole (im), Cd(NO3)2·4H2O and Ni(NO3)2·6H2O. The complexes were characterized by elemental analysis and FT-IR. Meanwhile, the crystal structures, fluorescence properties of complex 1 and thermogravimetrie analysis of complex 2 have been studied. In complex 1, 2,2'-dicarboxydiphenylthioether (EBLA) was prepared with 2,2'-dithiosalicylicacid (EBSA) in situ reaction by hydrothermal method. Complex 1 is a dinuclear structure and Cd2+ is five-coordinated in a distorted trigonal bipyramidal geometry. Complex 2 is a one-dimensional infinite linear chain and Ni2+ is six-coordinated to form a distorted octahedral geometry. Hydrogen bonding and π-π interactions are observed in these complexes.
