The structure of 1,7-heptanediamine dihydrobromide at 173 K, C7H18N2.2HBr

N-Benzyl-1-(dimethylamino)-2-methyl-1-oxopropan-2-aminium bromide

“…The HÁ Á ÁBr distance of 2.28 Å observed in (I) is of the same order of magnitude as in similar compounds of this type. A few examples of simple structures of this type are 1,7heptanediamine dihydrobromide (Brisson & Brisse, 1984a), 1,8-octanediamine dihydrobromide (Brisson & Brisse, 1984b;Baur & Tillmanns, 1986), iminodiacetic acid hydrobromide (Oskarsson, 1976) and tert-butylammonium bromide (Shabazi et al, 1992).…”
