摘要

H2L[N,N'-二(3-吡啶基)-2,6-吡啶羧酸二酰胺]与CuSO4·5H2O反应合成了新型大环双核铜配合物——[Cu2(H2L)2 (SO4)2(H2O)6]· CH3OH·6H2O(1),其结构经IR,XRD和元素分析表征.1属单斜晶系,空间群P21/C,晶胞参数a=26.870(5)(A),b=7.563 7(15)(A),c=28.316(6)(A),α=90°,β=114.91(3)°,y =90°.1在催化2,6-二甲基苯酚氧化偶联反应时表现出较好的选择性及催化活性.%A novel macrocyclic binuclear copper coordination, [ Cu2 (H2L)2 (SO4)2 (H2O)6] · CH3OH · 6H2O(1) , was synthesized by the reaction of CuSO4 · 5H2O with H2L[ N,N'-bis(pyri-dine-3-ylmethyl)pyridine-2,6-dicarboxamide]. The structure was characterized by IR, XRD and elemental analysis. 1 belongs to monoclinic system, space group P21/C with a =26. 870(5) A, b = 7.563 7(15) A, c=28.316(6) A, α =90°, β = 114.91(3)°, γ =90°. 1 possess good catalytic activity and selectivity in oxidative coupling of 2,6-dimethylphenol.
