摘      要：A new cadmium(Ⅱ) coordination polymer, [Cd(TITMB)_2]-(SO_4 )·21H_2O, whereTITMB = 1, 3, 5-tris (imidazol-1-yl-methyl) -2, 4, 6-trimethylbenzene, was obtained by self-assemblyof tripodal ligand TITMB with CdSO_4·2.7H_2O in acetonitrile, and characterized by X-raycrystallography. 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. Theresults of structure analysis indicate that each TITMB ligand coordinates three metal atoms and inturn each Cd(Ⅱ) atom with octahedral coordination geometry connects six nitrogen atoms of imidazolegroup from six different TITMB ligands to produce a 2D honeycomb network structure. There are a lotof water molecules linked by hydrogen bonds and occupied the channels formed intra- andinter-sheets.
