6-Chloro-2,4-bis(dimethylamino)-1,3,5-trimethylborazine
Acta Crystallographica Section E, 2013 The borazine ring of the title molecule, C7H21B3ClN5, shows a mild distortion from a planar to a flattened boat conformation. Steric effects due to the methyl and dimethylamine substituents appear to be the cause of this distortion.
