This paper computes the conductance of an open ellipse cavity and discusses the effect of finite leads on conductance. The lead introduces mode coupling with bound states in the cavity which contributes to Fano resonant line shapes in conductance. By examining the resonant states in the cavity, the effects of state mixing and annular probability distribution of wave function due to the presence of leads are found. The results have been compared with the transport properties of other systems. The finite leads result in two effects, i.e. the evanescent mode contribution and additional oscillations, to the conductance.
The hydrothermal reaction of 1,2-dicyanobenzene with NaN3 in the presence of CuC12, 2,2＇-bipyridine and H2O affords a novel dinuclear copper（Ⅱ）-ditetrazolate, [Cu（bpy）- （pdtz）]2 （Hpdtz = 5,5＂-1,2-phenylene-ditetrazole, bpy = 2,2＇-bipyridine）. The pdtz ligand is generated in situ through Sharpless 2＋3 cycloaddition reaction. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the monoclinic system, space group P211n with a = 8.2096（16）, b = 18.580（4）, c = 11.838（2） A, β = 103.12（3）°, V = 1758.5（6） A^3, Z = 2, Mr = 863.83, Dc = 1.631 g/cm^3, F（000） = 876 and μ = 1.272 mm^-1. In this novel dinuclear structure, the pdtz ligand adopts a peculiar μ2-η1,η2 coordination mode.
