采用水热合成反应,合成了含有多种氢键网络的Cu(Ⅱ)的配合物[Cu(C6H4NO2)2(H2O)3·H2O].对配合物的单晶进行了X光衍射分析.结果表明,在化合物中存在着3种氢键,使化合物晶体构成了无限延伸的三维网络结构,形成了超分子.晶体结构数据:晶体属三斜晶系,空间群为P1,晶胞参数为a=0.69577(5)nm,b=0.71428(10)nm,c=0.86691(6)nm;α=68.3860(12)o,β=68.439(5)o,γ=62.717(3)o,V=0.34554(6)nm3,Z=2,F(000)=193,Dc=1.816g/cm3,最终收敛因子:R=0.0269,ωR=0.0759.讨论了氢键在构建[Cu(C6H4NO2)2(H2O)3·H2O]超分子中所起的作用.并对化合物的红外吸收光谱和紫外可见吸收光谱进行了分析指认.
The Cu (Ⅱ) complex [Cu (C6H4NO2) 2 (H2O) 3 · H2O] containing many kinds of hydrogen bonds was synthesized by hydrothermal synthesis. The single crystal of the complex was analyzed by X-ray diffraction. The results show that there are three kinds of hydrogen bonds in the compound, which make the compound crystal form an infinite three-dimensional network structure and form a supramolecular crystal structure data: the crystal belongs to the triclinic system, the space group is P1, the unit cell parameter is a = 0.69577 (5) nm, b = 0.71428 (10) nm, c = 0.86691 (6) nm; α = 68.3860 (12) o, β = 68.439 (6) nm3, Z = 2, F (000) = 193, Dc = 1.816g / cm3 and the final convergence factor: R = 0.0269 and ωR = 0.0759. The formation of [Cu (C6H4NO2) 2 3 · H2O] supramolecules, and the infrared absorption spectra and UV-Vis absorption spectra of the compounds were analyzed and identified.
