The reaction of TMP-NH2 [TMP = m,m-(CF3)2-C6H3] with 2 equiv of n-BuLi led to the in situ formation of Li2[N-TMP], which, after the addition of BiCl3, formed a [Cl-Bi(μ3-N-TMP)]4-type heterocubane in up to 30% yield. Transmetalation reactions, thought of as alternatives, starting from the analogous tin-nitrogen heterocubane [Sn(μ3-N-TMP)]4 and BiCl3 resulted in the isolation of a complex reaction mixture from which different Bi-N and Bi-Sn-N cage compounds could be isolated. The structures of all cage compounds that contain bismuth are discussed, and the thermodynamics of the formation of [Cl-Bi(μ3-N-TMP)]4 are highlighted. In an attempt to isolate Li2[N-TMP], generated in situ from TMP-NH2 and 2 equiv of n-BuLi, it was possible to isolate a lithium salt with a negatively charged lithium cluster of the type [Li9(N-TMP)5F]2- with an unusual Li9N5F skeleton.

TMP-NH2 [TMP = m，m-（CF3）2-C6H3]与2当量的n-BuLi的反应导致Li2 [N-TMP]的原位形成，在加入BiCl3之后，形成[Cl-Bi（μ3-N-TMP）] 4型杂种菌，产率高达30％。从类似的锡-氮杂铜[Sn（μ3-N-TMP）] 4和BiCl3开始的重金属化反应被认为是替代方法，导致了复杂的反应混合物的分离，其中不同的Bi-N和Bi-Sn-N可以分离出笼状化合物。讨论了所有含铋的笼状化合物的结构，并突出了[Cl-Bi（μ3-N-TMP）] 4形成的热力学。为了分离从TMP-NH2和2当量的n-BuLi原位生成的Li2 [N-TMP]，
