Abstract

The novel precursor [Bu^tNHP(μ-NBu^t)₂PNH₂] (1) provides easy access to polycyclic main group systems; reaction with Sb(NMe₂)₃ gives the tricyclic species {[Bu^tNHP(μ-NBu^t)₂- P}₂{Me₂NSb(μ-N)}₂] (2), whereas reaction with an excess of BuⁿLi results in elimination of LiNH₂ and the formation of the co-complex [{Bu^tNP(μ-NBu^t)₂P}₂ N]Li₃ (BuⁿLi)₂, (3), containing the unprecedented [{Bu^tNP(μ-NBu^t)₂P}₂ N]³⁻ trianion.
