Abstract

The red crystalline complex [PhCH₂(Me)NNa(tmeda)]₂, synthesised from equimolar proportions of PhNa, the secondary amine PhCH ₂(Me)NH and the Lewis base tmeda (tetramethylethylenediamine, Me ₂NCH₂CH₂NMe₂), has been structurally identified by X-ray diffraction studies, which reveals a new type of structure based on a buckled (NNa)₂ dimeric ring with a cisoid arrangement of amido-substituents.
