摘要
Two cadmium（II） coordination polymers {[Cd（btp）（NO2-1,3-bdc）（H2O）]·H2O}n （1） and {[Cd（btp）（1,2-bdc）（H2O）]·H2O}n （2） were synthesized by the reaction of 1,3-bis（1,2,4-triazol-1-yl）propane （btp）, 5-nitroisophthalate （NO2-1,3-bdc）, and 1,2-benzenedicarboxylate （1,2-bdc）. 1 consists of undulated 2D （4,4） networks. Two identical undulated layers are parallel stacking to give a （2D→2D） polythreaded 2D network. A 3D supramolecular architectute is constructed through the hydrogen bond interactions. 2 has an unusual 2D （4,4） network with a thickness of ca. 10A. The btp ligands exhibit the anti-gauche conformation in 1 and the anti-anti conformation in 2. The flexible btp ligand exhibits the key role in the assembly of the topologies of 1 and 2. The luminescence and thermal stability were investigated.
