A new cadmium (II) coordination polymer, [Cd(TTTMB) 2 ]‐(SO 4 ) · 21H 2 O, where TTTMB =1,3, 5‐tris (imidazol‐1‐yl‐methyl)‐2,4,6‐trimethylbenzene, was obtained by self‐assembly of tripodal ligand TTTMB with CdSO 4 ·2.7H 2 O in acetonitrile, and characterized by X‐ray crystallography. The crystal data belongs to monoclinic space group C c with cell parameters a = 1.16891(4) nm, b =2.06671(6) nm, c = 2.48185(7) nm, β = 97.8560(10)°, R = 0.0487, wR = 0.1211. The results of structure analysis indicate that each TTTMB ligand coordinates three metal atoms and in turn each Cd(II) atom with octahedral coordination geometry connects six nitrogen atoms of imidazole group from six different TTTMB ligands to produce a 2D honeycomb network structure. There are a lot of water molecules linked by hydrogen bonds and occupied the channels formed intra‐ and inter‐sheets.
