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 Cu2 (-αfuroic acid) 4 (H2O) 4 was synthesized in methanol-water mixed solvent. The crystal structure of the crystal was determined. The crystal was monoclinic and the space group P2 (1) / c. = 1.0106 (4) nm, b = 1.046 (6) nm, c = 2.00790 nm; β = 91.118 (8) °, V = 2.646 (2) nm3, Dc = 1.619 g / cm3, Z = 4, ) = 1306. The final deviation factor R1 = 0.0567, wR2 = 0.1676, the two Cu (II) bridged by four furofuranate and its end have a water molecule coordination, forming a distorted quadrangular pyramid with Bit environment. The Cu (II) -Cu (II) complex has a center of symmetry and its Cu (II) -Cu (II) spacing is 0.2637 nm. The electrochemical properties of the complex have been studied by crystal structures.
