Abstract
n-Butyllithium reacts with a solution of PhNC(Ph)NHPh (N,N'-diphenylbe nzamidine) and NMe[(CH2)2NMe2]2 (pmdeta) to give the complex LiCPh(NPh )2.pmdeta, which is monomeric in the solid state with a five-co-ordina te lithium cation bound to a tridentate pmdeta ligand and a bidentate amidinide anion (diazaallyl system, chelating), in which the two N-C b ond lengths of 1.336(4) and 1.335(4) angstrom suggest almost uniform d elocalisation along the N-C-N unit.
