Abstract

The compound (o-LiC6H4CH2·NLi·CH2CH2NMe2)n(1) is tetrameric (n= 4) in the crystal, with a core of three edge-connected Li4 tetrahedra bonded by N(Me2)Li, µ-N-amido-Li, o-C–Li, η2-o-C–m-CH–Li, and η3-CH2–α-C–o-C–Li interactions; in addition, the Li8 array displays some extremely short Li Li contact distances and coupling of Li atoms in solutions of (1) has been detected by homonuclear 7Li COSY n.m.r. spectroscopy.
