摘要
合成了新配合物Cu(teta)(PF6)2(teta=内消旋5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环十四烷),并且经元素分析、红外光谱和电子吸收光谱表征,其结构通过单晶X-射线衍射法确定.该配合物属单斜晶系,空间群P21/n.晶胞参数a=0.8465(5),b=0.9093(6),c=1.6418(11)(nm),β=97.227(10)°,V=1 2537(14)nm3,Z=2,ρcalc=1 690g/cm3,F(000)=654.00.最后的偏差因子R1=0 097,wR2=0 190[I>2σ(I)].铜原子位于配合物的对称中心,与teta的四个氮原子呈平面正方形配位.
The complex Cu(teta)(PF_6)_2 (teta=meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) was synthesized and characterized by elementary analysis, IR and UV and the structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2_1/n with a =0.8465(5),b = 0.9093(6),c = 1.6418(11)nm,β= 97.227(10)°,V = 1.2537(14) nm^3,Z=2,ρ_(calc) =1.690 g/cm^3,F(000) = 654. The complex has the centrosymmetry and the copper(Ⅱ) ion is located in the center. The copper(Ⅱ) ion co-ordinates with four nitrogens of the macrocycle in square planar environment.
