摘要
在甲醇水混合溶剂中合成了标题配合物Cu2(-αfuroic acid)4(H2O)4,测定了其晶体结构,晶体属单斜晶系,空间群P2(1)/c,晶胞参数:a=1.0106(4)nm,b=1.046(6)nm,c=2.00790nm;β=91.118(8)°,V=2.646(2)nm3,Dc=1.619g/cm3,Z=4,F(000)=1306.最终偏离因子R1=0.0567,wR2=0.1676,两个Cu(II)由四个呋喃甲酸根桥联且其端位各有一个水分子配位,形成一个具有畸变的四角锥形配位环境。配合物中Cu(II)-Cu(II)间具有一对称中心,其Cu(II)-Cu(II)的间距为0.2637nm,结合晶体结构对配合物进行了电化学性质研究。
The title complex has been synthesized by a-furoic acid and cupric carbonate monohydrate in the solvent mixture of water and methanol. It crystallizes are monoclinic, space group P2 (1)/c, with a = 1. 0106 (4), b = 1. 3046 (6), c = 2. 00790nm;β=91.118(8)°, V=2.646(2)nm^3, Dc=1.619g/c^m3, Z=4 ,F(000)=1306. lead to the reliability factor R1 = 0. 0567, wR2 = 0. 1676. The crystal structure shows that each copper(Ⅱ) atom is coordinated with five oxygen atoms from one water and four a-furoic acids, forming a distorted square pyramidal configuration. There is asymmetric center between the two copper (Ⅱ) atoms. The Cu-Cu bond distance is 0. 2637nm. The cyclic voltammetric behavior of the complex is reported.
