本文报道了[Cu(2,2’-联吡啶)_2Cl](BF_4)配合物的合成和晶体结构。晶体属单斜晶系,空间群P2_1/n,晶胞参数为:a=10.761(1),b=12.069(1),c=16.146(3)A,β=104.7(1)°,Z=4。在CAD-4四园衍射仪上收集衍射强度数据;重原子法解出结构,并经全矩阵最小二乘法修正结构,最后的偏离因子R=0.05,R_W=0.058。 结构测定得出[Cu(2、2’-bpy)_2Cl]~+配阳离子中的Cu原子为五配位的,它是由两个2,2’-联吡啶上的4个N原子和1个Cl原子配位而成。CuN_4Cl配位球略有畸变的三方双锥的构型。
In this paper, the synthesis and crystal structure of Cu (2,2’-bipyridyl) _2Cl] (BF_4) complexes have been reported. The crystal belongs to the monoclinic system with space group P2_1 / n. The unit cell parameters are a = 10.761 (1), b = 12.069 (1), c = 16.146 (3) A, β = 104.7 4. Diffraction intensity data were collected on a CAD-4 four-Park diffractometer; the structure was solved by the heavy atom method, and the structure was corrected by the full matrix least-squares method. The final deviation factor was R = 0.05 and R_W = 0.058. The structure determination results in a Cu (2,2’-bpy) _2Cl] ~ + Cu atom in the cation with pentacoordination. It consists of four N atoms on two 2,2’-dipyridyls and one Cl atoms formed. CuN_4Cl coordination sphere slightly distorted triple bipyramid configuration.
