Hydrothermal Synthesis,Crystal Structure and Properties of a Novel 2-D Grid-like CdⅡ Metal-organic Framework

摘要

A novel Cd(Ⅱ) coordination polymer,{[Cd3(tzo)2(suc)(H2O)6]·(suc)}n (Htzo = 1,2,4-triazole,H2suc = succinic acid),has been synthesized from the reaction of aqueous solution of niques,and structurally characterized by X-ray analysis and spectral techniques.To the best of our knowledge,among the few documented triazole-cadmium coordination polymers,this complex presents a novel configuration.The deprotonated 1,2,4-triazole is in tridentate and succinate in bis-chelate modes to link the Cd(Ⅱ) centers,generating a 2-D grid-like network topology.Thermogravimetric analysis results show that the framework architecture is a stable porous material.The fluorescent emission has also been discussed.
