Lithium structural chemistry continues to surprise as highlighted here by the reaction of BunLi, ... more Lithium structural chemistry continues to surprise as highlighted here by the reaction of BunLi, aniline and pmdeta, which by analogy with related systems, should yield a simple monomeric complex, when, in fact, an unprecedented trinuclear formulation is produced; in contrast, the corresponding Na system falls into line with predictions, in yielding a dimeric product.
