合成了一系列钠铝氮杂三环配合物Na（3）L（THF）（5）（1），[AlLMe][Na（4）L（THF）（6）]（2），AlL（THF）（3），AlNaLMe（THF）（2）（4），和AlNaLOBn（THF）（2）（5），其中L =三（2-氧-4，6-二叔丁基苄基）胺，并通过NMR，X-射线晶体学和元素分析进行了表征。Na（3）L（THF）（5）（1）的三核钠三环配合物在室温下是不稳定的，而配合物2中的四核钠三环阳离子由于-[Na-O-benzene]（3）-的强相互作用环而被多金属协同效应稳定。络合物2也是钠氮杂三环和铝氮杂三环离子配对络合物的第一个实例，其中阳离子和阴离子部分都含有氮杂三环配体。
A series of sodium and aluminum atrane complexes of Na(3)L(THF)(5) (1), [AlLMe][Na(4)L(THF)(6)] (2), AlL(THF) (3), AlNaLMe(THF)(2) (4), and AlNaLOBn(THF)(2) (5), wherein L = tris(2-oxy-4,6-di-tert-butyl-benzyl)amine, were synthesized and characterized by NMR, X-ray crystallography, and elemental analysis. The trinuclear sodium atrane complex of Na(3)L(THF)(5) (1) is labile at room temperature; however, the tetranuclear sodium atrane cation in complex 2 can be stabilized by a multimetallic synergetic effect due to a firm interaction ring of -[Na-O-benzene](3)-. Complex 2 is also the first example of a sodatrane and alumatrane ion-paired complex in which both the cationic and anionic moieties contain an atrane ligand.
