[{[PhC(H)- N - C(H)Ph]K--(+). pmdeta}(infinity)] adopts a novel crystal structure exhibiting separate eta(3)-C - N - C and eta(3)-C - C - C ligating modes, surprisingly leaving one electronegative N centre not bonded to K+; reaction of the azaallyl K with its parent imine PhC(H)=NCH(2)Ph in toluene affords the interesting, metal-free, chiral product PhC(H)=NCH(Ph)CH(Ph)N(H)CH(2)Ph.
