A 3:1 mixed aggregate of diphenylamidolithium with lithium chloride:crystal structure of [(Ph2NLi)3LiCl·3tmen] (tmen = N,N,N′,N′-tetramethylethylenediamine)

Abstract

Demonstrating a new structural type in mixed aggregate chemistry, a 3:1 mixture of Ph₂NLi and LiCl with 3 equiv. of N,N,N′,N′-tetramethylethylenediamine exists in toluene and in the solid state as a Ph₂NLi/LiCl mixed ‘dimer’ and a (Ph₂NLi)₂ homodimer linked only by a Li–Cl coordinate bond, as determined by NMR spectroscopy and X-ray crystallography.
