摘要： 合成了3个分别以C2O42-([Cu2(L1)2(ox)],1),AcO-([Cu2(AcO)(L2)2]BF4,2)和酚氧([Cu2(L3)2](ClO4)2,3)为桥基的双核铜配合物,并测定了1的复配合物[Cu2(L1)2(ox)]·[Fe(OH)2(H2O)4]ClO4·H2O(1')及2和3的晶体结构.X射线衍射结果表明:1',2和3分别属于Fddd,P21/c和P21/c空间群.晶胞参数:[Cu2(L1)2(ox)][Fe(OH)2(H2O)4]ClO4·H2O,α＝2.4390(4)nm,b＝3.0538(6)nm,c＝1.8494(6)nm,α＝β＝γ=90.00°;2,α＝0.847(1)nm,b＝2.6542(8)nm,c=1.4100(6)nm,β＝91.34(6)°;3,α＝0.7646(3)nm,b=1.6983(3)nm,c＝2.4417(3)nm,β＝97.11°.

Abstract: Three dinuclear Cu(Ⅱ) complexes with oxalate (Cu2(L1)2(ox), 1), acetate (Cu2(AcO)(L2)2 BF4, 2) and phenolate group(Cu2(L3)2 (ClO4)2, 3)as bridging group, individually, were synthesised, and the crystal structures of composite complex Cu2(L1)2(ox) · Fe(OH)2(H2O)4 ClO4·H2O (1') and complexes 2 and 3 were determined. X-ray crystal structure analyses comfirm that the crystals of 1', 2 and 3 exist in Fddd, P21 / c and P21 / c space group, respectively. The crystal cell parameters of 1' are: a =2.4390(4) nm, b = 3.0538(6) nm, c =1.8494(6) nm, α=β=γ =90.00° and these of 2 are:a =0.847(1) nm, b =2.6542(8) nm, c =1.4100(6) nm, β =91.34(6)°; 3: a =0.7646(3) nm, b =1.6983(3) nm, c =2.4417(3) nm, β =97.11°. Electrochemical investigations of 1 and 3 show that bicopper(Ⅱ) centre experiences a mix-valence species during the course of reduction scan.
