A series of novel copper (II), cadmium (II), and silver (I) coordination frameworks, {[CuL2(H2O)(2)]center dot 2(ClO4)center dot 2H(2)O}(n)(1), {[CdL2(H2O)(2)]center dot 2(ClO4)center dot 2H(2)O}(n)(2), and [AgL center dot CF3SO3](n)(3) based on 3,5-bis-(triazol-1-yl)pyridine(L), have been isolated and characterized by single-crystal X-ray diffraction. In1and2, the bi-dentate L bridges neighboring Cu(II)centers and Cd(II)centers generating the one-dimensional (1D) double-chain cationic coordination polymer, in which lattice-free ClO(4)(-)and lattice water molecules are located between these neighboring 1D chains. In3, these tri-dentate L bridge neighboring Ag(I)centers, which construct the two-dimensional (2D) coordination framework. The terminal coordinated CF(3)SO(3)(-)anions are decorated along the side of the 2D framework. Further,1also presents the novel example of cationic triazole-copper (II) coordination polymer for effectively capturing anion pollutants Cr(2)O(7)(2-)in the water solutions. The solid-state luminescent properties of L and coordination polymers2-3were also investigated.
