The title compound, C 14 H 24 N + ÁI À , was formed by a Schiff base condensation of 2,6-diisopropylaniline and acetone, using GaI as a Lewis acid. A strong interaction from the iminium hydrogen NÐH to the iodide counter-ion is observed. The 1 H and 13 C NMR data are also reported.
The ortho-disubstituted aromatic ring in the title compound, C 27 H 32 N 2 , is twisted by 76.1 (1) with respect to the isopropylsubstituted ring and by 89.3 (1) with respect to the methylsubstituted ring. The amino N atom is linked intramolecularly to the imino N by a hydrogen bond [NÁ Á ÁN = 2.686
