Abstract

Two Crystalline adducts of sodium amide 1 and 2 adopt contrasting binuclear structures, as revealed by X‐ray diffraction. Thus, the bidentate anions are linked to the Na ions in a terminal manner in 1 but in a bridging manner in 2. Each structure also displays unusual donor‐acceptor coordinations, with PA bridging to Na in 1, while only two of the three available PMDETA nitrogen centers complex to Na in 2. (Formula Presented.)
