新型五配位铝加合物Me（2）HN. AlL（2）[其中L =三（2-氧-3，5-二甲基苄基）胺]含有三个六元环，已用光谱和X射线方法表征。这种铝三环的加合物是第一个结构特征的单体铝三环衍生物，与其母体铝三环[Al（OCH（2）CH（2））（3）N]（x）不同，2在气体、溶液和固体状态下都是单体。2的X-射线分子结构揭示了一个C（3）对称的三环笼状部分。铝的几何形状是一个稍微扭曲的三角双锥，其中，非常出乎意料的是，金属原子位于由三个赤道氧形成的平面下方，并且其Al-N（叔）键比Me（3）N.AlH（3）.NMe（3）中的短（Heitsch，C.

The novel five-coordinate aluminum adduct Me(2)HN. AlL (2) [wherein L = tris(2-oxy-3,5-dimethylbenzyl)amine] containing three six-membered rings has been characterized by spectroscopic and by X-ray means. This adduct of an alumatrane is the first structurally characterized monomeric alumatrane derivative, and unlike its parent alumatrane [Al(OCH(2)CH(2))(3)N](x), 2 is monomeric in the gas, solution, and solid states. The X-ray molecular structure of 2 reveals a tricyclic cage moiety of C(3) symmetry. The aluminum geometry is a slightly distorted trigonal bipyramid in which, quite unexpectedly, the metal atom is located somewhat below the plane formed by three equatorial oxygens and its Al-N(tertiary) bond is shorter than that in Me(3)N.AlH(3).NMe(3) (Heitsch, C. W.; Nordman, C. E.; Parry, R. W. Inorg. Chem. 1963, 2, 508).
