摘      要：Two new coordination polymers(CPs) based on two new tetrazole-based ligands, namely, [Cu(TPP)]n(HTTP = 4-(3-(2 H-tetrazol-5-yl)phenyl)pyridine, 1) and {[Cd_2(TBCA)_2(H_2O)_2]·-H_2O}n(H_2TBCA = 3?-(2 H-tetrazol-5-yl)biphenyl-4-carboxylic acid, 2), were synthesized via solvothermal reactions. Single-crystal X-ray diffraction analysis reveals that compound 1 exhibits a(3,6)-connected rtl network topology based on binuclear secondary building units(SBUs). Compound 2 presents a 2D framework composed of 1D SUBs formed by both carboxyl and tetrazole groups. The 2D network is linked into a 3D framework via various hydrogen bonds. They represent two examples of CPs construct from rigid 5-substitued tetrazole-based ligands with relatively longer spacer. The thermal stabilities and luminescent properties of compounds 1 and 2 were also explored.
