A Cd(Ⅱ) complex constructed by mixed ligands oxalic acid and HL, [Cd(L)(C2O4)oi(H2O)]n (HL=4-(imidazol-1-yl)benzoic acid), has been synthesized under hydrothermal conditions and characterized by elemental analyses, IR spectrum and single crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21, a= 1.167 60 (14) nm, b=0.841 80(15) nm, c=1.246 90(15) nm,β=105.404(2)°, V=1.181 5(3) nm3, Z=4, R1=0.031 2, wR2=0.063 1. The titled complex includes a grid-like 2D layer. Three sets of these 2D layers interpenetrate with each other to construct a three-fold interpenetrating structure. Furthermore, the photoluminescence property of the titled complex has also been studied.
