Construction of a Set of Cadmium（Ⅱ） Coordination Polymers with Atza and 2,2′-Bipy or 1,10-Phen Ligands （Atza=5-Aminotetrazole-1-acetato Anion）

Reactions of CdX2(X=NO3-, ClO4-) with Hatza (atza=5-aminotetrazole-1-acetato anion) and 2,2′-bipyridine (2,2′-bipy) or 1,10-phenanthroline (1,10-phen) in a methanol/aqueous solution produced a set of new Cd(Ⅱ) coordination polymers, {[Cd(atza)(H2O)(2,2′-bipy)]ClO4}n (1), {[Cd(atza)(H2O)(1,10-phen)]ClO4 }n (2), {[Cd(atza)(H2O)(2,2′-bipy)]NO3}n (3) and {[Cd(atza)2 (1,10-phen)]·0.5H2O}n (4). Single-crystal X-ray diffraction analysis reveals that each Cd(Ⅱ) ion has a distorted octahedral coordination geometry in 1-4, and the Cd(Ⅱ) ion centers are connected through the tridentate atza bridging ligands to form a 2D layer (1-3) or ID chain (4) structure. The fluorescent properties of 2 and 4 are also discussed.
