摘　　要：A new coordination polymer [Cd2（5-IPA）（HL）2（H20）2]＇4H20 （1） was prepared under hydrothermal conditions based on 5-hydroxy-isophthalic acid （5-H2IPA） with multi-N-donor ligand 1-（1H-imidazol-4-yl）-3-（4H-tetrazol-5-yl）benzene （H2L）. The complex was characterized by IR spectroscopy, TGA, X-ray powder and single-crystal diffraction. It crystallizes in the monoclinic system, space group C2/e with a = 23.6291（18）, b = 9.9847（8）, c = 17.7244（14） A, fl = 124.6180（10）°, V = 3441.4（5） A3, Z = 4, C28H30N12O11Cd2, Mr = 935.44, Dc = 1.805 g/cm^3,μ= 1.313 mm^-1, S = 1.055, F（000） = 1864, the final R = 0.049 and wR = 0.1315 for 2985 observed reflections （I 〉 2σ（I））. The central metal Cd（II） atoms with octahedral coordination geometry are six-coordinated by three oxygen and three nitrogen atoms. The HL- ligands from the deprotonated HzL connect Cd（II） atoms to form two-dimensional （2D） double-layer fes networks which are further pillared by 5-IPA2- ligands into a rare binodal （3, 4）-connected three-dimensional （3D） architecture with a （4·6·8）（4·62·83） fse-3,4-C2/c topology. Solid state luminescent property and sorption property of 1 have been investigated.A new coordination polymer [Cd2（5-IPA）（HL）2（H20）2]＇4H20 （1） was prepared under hydrothermal conditions based on 5-hydroxy-isophthalic acid （5-H2IPA） with multi-N-donor ligand 1-（1H-imidazol-4-yl）-3-（4H-tetrazol-5-yl）benzene （H2L）.
