摘要：

A new three-dimensional porous metal-organic framework, {[NH2(CH3)(2)][Zn(atz)(ox)]center dot H2O}(n) (1) (Hatz = 5-amino-1H-tetrazole, H(2)ox = oxalic acid), has been solvothermally synthesized and characterized by elemental analysis, IR, TG, and single-crystal X-ray diffraction analysis. Complex 1 exhibits an anionic framework that can be simplified as a rarely reported 4-connected lon network. Complex 1 could be utilized as a platform for emission tuning by doping different lanthanide ions. In addition, gas adsorption studies reveal that 1 has a high isosteric heat of CO2 and good adsorption selectivity for CO2 over CH4 and N-2.
