用模板法合成了1个大环金属铜(Ⅱ)配合物[CuLCl2]·3H2O(1)和3个大环金属镍(Ⅱ)配合物[NiLCl2](2),[NiL](ClO4)2(3)和[NiLH2](ClO4)4(4)(L=3,10-二乙基-1,3,5,8,10,12-六氮杂十四烷),通过X-射线衍射单晶结构分析测定了它们的晶体结构。晶体结构显示:配合物1和2的金属离子与大环配体的4个氮原子及大环平面轴向的2个氯离子以八面体配位方式配位:配合物3和4的金属离子与大环配体的4个氮原子以平面正方形配位方式配位,配合物4的侧链氮原子的质子化导致侧链结构翻转。使得其侧链与大环平面共面。
One macrocyclic Cu(Ⅱ) complex of [CuLCl2]· 3H2O (1) and three macrocyclic Ni(Ⅱ) complexes of [NiLCl2] (2), [NiL](ClO4)2 (3), [NiLH2](ClO4)4 (4) (L=3,1O-bis(2-ethyl)-1, 3, 5, 8, 10, 12-hexaazacyclotetradecane) have been synthesized and structuraⅡy characterized by X-ray diffraction single crystal structural analysis. Each metal ion in 1 and 2 is six-coordinated with four macrocyclic nitrogen atoms in the equatorial plane and two chloride anions in axial positions. Each nickel ion in 3 and 4 is planar four-coordinated with four macrocyclic nitrogen atoms, The orientations of ethyl pendant groups in 4 are different from those in 1-3 due to the protonation of the two tertiary amines in 4.
