以硝酸铜和对氯苯氧乙酸为原料,合成了标题化合物[Cu(C8H6ClO3)2(H2O)2],并用元素分析仪、红外光谱仪、X射线单晶衍射仪表征了其组成和晶体结构.结果表明,所合成的晶体属三斜晶系,Pī空间群,a=0.511 46(6)nm,b=0.706 40(8)nm,c=1.326 410(15)nm,α=81.777 0(10)°,β=86.361(2)°,γ=76.397 0(10)°,F(000)=239,Z=1;最终偏离因子R=0.026 4,wR=0.067 4.在配合物中,铜离子与来自两个对氯苯氧乙酸根的两个羧基氧原子、两个醚氧原子以及来自两个水分子的氧原子配位,形成变形八面体结构.
The title compound [Cu (C8H6ClO3) 2 (H2O) 2] was synthesized from cupric nitrate and p-chlorophenoxyacetic acid. Its composition and crystal structure were characterized by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction. The results show that the synthesized crystal belongs to triclinic system, the space group of Pī is a = 0.511 46 (6) nm, b = 0.706 40 (8) nm, c = 1.326 410 ), Β = 86.361 (2) °, γ = 76.397 0 (10) °, F (000) = 239, Z = 1; final deviation factor R = 0.026 4, wR = 0.067 4. In the complex, Ions coordinate with two carboxyl oxygen atoms, two ether oxygen atoms from two p-chlorophenoxyacetates and oxygen atoms from two water molecules to form a deformed octahedral structure.
