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 = 4,4?-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.
