| 摘要: 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。 |

| Abstract: 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=3,10-bis(2-ethyl)-1, 3, 5, 8, 10, 12-hexaazacyclotetradecane) have been synthesized and structurally 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. CCDC: 289431, 1; 289432, 2; 289433, 3; 289434, 4. |
