Two coordination polymers, [Zn(Btec)0.5(H2L)]n (I) and [Cd0.5(Tp)0.5(H2L')(H2O)]nnH2O (II) (H2L = 3-(1H-pyrazol-4-yl)-5-(pyridin-2-yl)-1,2,4-triazole; H4Btec = 1,2,4,5-benzenetetracarboxylic acid; H2L' = 3-(1H-pyrazol-4-yl)-5-(pyridin-3-yl)-1,2,4-triazole; H2Tp = terephthalic acid), have been synthesized under hydrothermal conditions. The title compounds were structurally characterized by elemental analysis, single crystal X-ray diffraction analysis, infrared spectra. Compounds I and II crystallize in the orthorhombic and triclinic, space group Pbca and P¯1, respectively. Compound I displays a two-dimensional plane structure, those are connected by N···H···O hydrogen bonds to generate 3D frameworks. Compound II is constructed a 1D chain structure by Tp2− ligands, which are connected into 2D structure by the hydrogen bonds. In addition, the fluorescent property of I has been studied in the solid state at room temperature. The thermal analysis of I has also been investigated.
