| Abstract: Two coordination polymers [Zn(EBLA)(2,2'-bipy)(H2O)] (1) and [Mn(EBSA)(im)2(H2O)]n (2) were synthesized by hydrothermal and evaporation methods using2,2'-dithiosalicylic acid(EBSA), 2,2'-dipyridyl, imidazole, Zn(NO3)2·6H2O and Mn(NO3)2·4H2O. And the complexes were characterized by elemental analysis, FT-IRand thermogravimetrie analysis (TGA), meanwhile the crystal structures and fluorescence properties of the complex 1 have been studied. In complex 1, 2,2'-dicarboxydiphenylthioether (EBLA) was prepared with 2,2'-dithiosalicylic acid(EBSA) in situ reaction by hydrothermal method. The complex 1 is a dinuclear structure and Zn2+ ion is five-coordination in a distorted square pyramidal geometry; The complex 2 is a one-dimensional infinite linear chain and Mn2+ ion is six-coordination in a distorted octahedral geometry. Hydrogen bonding and π-π interactions are observed in these complexes. CCDC: 998513, 1; 1000616, 2. | |
