Complex 1 crystallizes in monoclinic system, space group P21 /c, a = 10.893（2）, b = 7.3641（15）, c = 1.9921（4）, β = 92.16（3）, V = 1596.9（6）3, Dc = 1.676 g/cm3, Mr = 402.84, Z = 4, F（000） = 820, μ = 1.404 mm-1, the final R = 0.0237 and wR = 0.0693. The Cu（II） ion is five-coordinated by two O atoms from two pdc ligands, one N atom from another pdc ligand and two N atoms from the bpy ligand. The pdc anion, which acts as a tridentate ligand, links three Cu ions, forming（3,3）-connected two-dimensional（2D） sheets. We also studied the electronic structure and orbital energies of complex 1 by DFT methods, and the results are consistent with UV-vis spectrum.展开更多

The structure was characterized by elemental analysis, IR and 1H NMR spectra, and the crystal structure was determined by X ray single crystal diffraction analysis. The crystal belongs to monoclinic space group P 2 1/ n, a =0 96250(19) nm, b =1 0947(2) nm, c =1 9965(4) nm, β =92 31(3)°, Z =2, V =2 1019(7) nm 3, D c=1 574 g/cm 3, μ =1 248 mm -1 , F (000)=1000, R 1=0 0675, wR 2=0 0836. In the crystals of the complex, each tin atom is seven coordinated in a distorted bipyramidal structure.展开更多
