Syntheses and structures of an unsolvated tetrakisimidophosphate (Li3(P(NBut)3(NSiMe3))2 and the face-sharing double-cubane (Li2(THF)[P(O)(NBut)2(NHBut)])2. | LitMetric

The treatment of Me3SiN=P(NHBut)3 with three equivalents of LiBun in toluene produces (Li3(P(NBut)3(NSiMe3)))2 comprised of a Li6N6 cyclic ladder capped on the two hexagonal faces by mu 3-PNSiMe3 groups; the corresponding reaction of O=P(NHBut)3 yields the face-sharing double-cubane (Li2(THF)P(O)(NBut)2(NHBut))2 with a central Li2O2 ring.
