摘要
Two new coordination polymers containing rigid bis（triazole）, namely, [Ni（btb）_（0.5）（nph）（H_2O）]_n（1） and [Zn（btb）（SO_4）]_n（2）（btb = 4,4a-bis（1,2,4-triazolyl-1-yl）-biphenyl, H_2nph = 3-nitrophthalic acid） have been synthesized and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. Complex 1 shows a 3D trinodal（3,4,4）-connected sqc69 topology. Complex 2 presents a 2D uninodal 4-connected sql network, which is further packed into a 3D supramolecular framework by C-H···O hydrogen bonds. Thermal stabilities and fluorescence properties of two complexes have been discussed in detail.
