| Abstract: | Three two-dimensional coordination polymers [Cd(2,3-Pyma)Cl2] n (I), {[Cd(2,3-Pyma)(1,4-Chdc)] · 4H2O}n (II) and {[Zn2(2,3-Pyma)(1,2,4,5-Bttc)(H2O)4] · 6H2O} n (III) (2,3-Pyma = (2,3-pyridylmethyl) amine, H2-1,4-Chdc = 1,4-cyclohexanedicarboxylic acid, and H4-1,2,4,5-Bttc = 1,2,4,5-benzenetetracarboxylic acid) have been synthesized and structurally characterized by single crystal X-ray crystallography (CIF files CCDC nos. 989461 (I), 1055685 (II) and 1055686 (III)). Three complexes are all twodimensional layer networks bridged by the flexible 2,3-Pyma ligands or the carboxylate ligands. It is noted that the flexible 1,4-Chdc ligands bind the Cd2+ ions into a helical chain structure in complex II. The photoluminescence and thermal properties are investigated. |
