A new three-dimensional Zn2 + coordination polymer constructed from oxalate and 1,2,4-triazolate

• A Zn2 + CP was solvothermally synthesized.
• Its structure was revealed.
• Its sensing ability on NB was investigated.

A new 3-D Zn2 + coordination polymer (CP) [(CH3)2NH2]3[Zn6(ox)4.5(trz)6]⋅ 4H2O (ox = oxalate; trz = 1,2,4-triazolate) 1 was obtained by a simple solvothermal self-assembly. The crystal structural analysis demonstrates that the trz molecules link the Zn2 + ions into a two-dimensional (2-D) layer network, which is based on the trinuclear Zn3(trz)6 clusters. The ox molecules serve as the linkers to propagate the 2-D layers into a three-dimensional (3-D) network of 1. The thermogravimetry (TG) behavior, photoluminescence property, and the sensing ability of 1 are investigated. The sensing experiment on nitrobenzene (NB) reveals that 1 can serve as a fluorescence probe to detect NB at the ppm concentration.
