Abstract
A new metal-organic frameworks (MOFs), [Cd-3(Pmb)(2)(bpdC)(2)] 2H(2)O (1) (pmb = 3,5-bis(4-pyridylmethylenoxyl)benzoate, bpdc = 2,2'-biphenyldicarboxylate), has been synthesized by hydrothermal method and structurally characterized through IR, TG and single-crystal X-ray analysis. The infinite wave-like 1 D metal-oxygen chains made by Cd3N4O12 clusters in 1 bridged by the carboxylate of bpdc ligand, construct a 21) framework in which interesting meso-helical chains are constructed by metal centers and pmb ligands, Solid state luminescent spectrum of I also has been investigated at room temperature.
