Graphycal Abstract: A new cadmium(II) polymeric complex was synthesized under solvothermal conditions by the reaction of 5-(4-carboxy-5-methyl-1H-1,2,3-triazol-1-yl)isophthalic acid (H3L) with cadmium nitrate tetrahydrate in a mixture of N,N-dimethylacetamide and water. The polymeric complex is an infinite 2D coordination polymer with the general formula {[Cd3L2(H2O)6]·2H2O}n. The two-dimensional coordination polymer {[Cd3L2(H2O)6]}n presents p–p stacking interactions between benzene rings of adjacent 2D coordination polymers, which contribute along with numerous O-H---O H-bonds to the assembly of a 3D supramolecular assembly. The intense photoluminescence emission of cadmium(II) complex is observed in the blue-violet region of the spectrum.
