The result shows that the complex crystallizes in monoclinic, space group P21 / c with a=0.695 7(4) nm, b=0.988 7(4) nm, c=1.974 8(7) nm, β=91.934(19)°, V=1.357 5(10) nm3, Z=4, Dcalc=1.831 g·cm-3, F(000)=752, μ=1.50 cm-1, the final R=0.036 6, wR=0.091 0. The coordination environment of Ag髣 is nearly linear with two N atoms, and each L ligand links two Ag髣 atoms using its two imidazolyl N atoms to generate an infinite one-dimensional (1D) chain structure. The 1D chains are further connected by C-H.O hydrogen bonds to give a three-dimensional structure. CCDC: 609514.展开更多

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.展开更多
