A structural study of 2,4-di-methyl-aniline derivatives.

Crystallographic studies of nitro-gen-containing small mol-ecules aid in the elucidation of their structure-activity relationships and modes of aggregation. In this study, two previously synthesized mol-ecules are crystallographically characterized for the first time. Reaction of 2,4-di-methyl-aniline with -bromo-succinimide affords the -brominated derivative 2-bromo-4,6-di-methyl-aniline (; CHBrN), which sublimates to afford crystals featuring hydrogen-bonded chains as well as Type I halogen-halogen inter-actions.
