| Popis: | One three-dimensional coordination polymer material, {[Cu3(nbta)2(bpfp)2(H2O)2](H2O)2}n (H3nbta = 5-nitro-1,2,3-benzenetricarboxylic acid, bpfp = bis(4-pyridylformyl)piperazine), is synthesized and structurally characterized. X-Ray structural analysis shows that the compound exhibits a three-dimensional structure featuring an unusual 3-nodal 4-connected topology. The compound is further characterized by elemental analysis, infrared spectrum, thermogravimetric analysis, and UV–vis absorption spectrum. Importantly, the compound exhibits efficient heterogeneous catalytic activity to the Knoevenagel reaction at room temperature. Moreover, the recyclability and heterogeneity of the reaction were also explored. |
