Synthesis, crystal structure and luminescence studies of zinc() and cadmium() complexes with 6-(1-tetrazol-5-yl)-2-naphthoic acid

Two coordination polymers (CPs) with a novel bifunctional ligand, [ZnL] n ( 1 ) and [CdL(H 2 O)] n ( 2 ), (L = rigid 6-(1 H -tetrazol-5-yl)-2-naphthoic acid), have been synthesized and structurally characterized, which reveal that the two constructed CPs exhibit three dimensional structures. The two...

Description
Summary:Two coordination polymers (CPs) with a novel bifunctional ligand, [ZnL] n ( 1 ) and [CdL(H 2 O)] n ( 2 ), (L = rigid 6-(1 H -tetrazol-5-yl)-2-naphthoic acid), have been synthesized and structurally characterized, which reveal that the two constructed CPs exhibit three dimensional structures. The two CPs consist of a one-dimensional Zn-tetrazole chain and a double-layered two-dimensional Cd-tetrazole structure. In addition, IR, elemental analysis, and luminescent spectra of 1 and 2 were also examined. At room temperature, 1 exhibits an intense emission at around 421 nm upon 370 nm excitation, whereas 2 exhibits an intense emission at 381 nm upon 350 nm excitation. Through variable-temperature luminescent and quantum calculations, the blue-shift of the peaks from the ligand and 1 and 2 is ascribed to the different configurations of L caused by the different coordination environments of the metal ions. Two coordination polymers have been synthesized and structurally characterized, which exhibit different luminescent properties caused by the different coordination environments of the metal ions.
