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 ...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.展开更多
