Hydrothermal synthesis, crystal structure and properties of a novel 2-D grid-like CdII metal-organic framework

A novel Cd(II) coordination polymer, {[Cd-3(tzo)(2)(suc)(H2O)(6)]center dot(suc)}(n) (Htzo = 1, 2, 4-triazole, H(2)suc = succinic acid), has been synthesized from the reaction of aqueous solution of Cd(NO3)(2)center dot 4H(2)O with a 1:1 mixture of disodium succinate and 1,2,4-triazole by hydrothermal techniques, 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.
