Abstract
The perchlorate salt of the histamine dication [systematic name: 4-(2-azaniumylethyl)-1H-imidazol-3-ium bis(perchlorate)], C5H11N32+·2ClO4−, crystallizes in the monoclinic space groupP21/cwith two formula units in the asymmetric unit. One of the histamine dications is disordered [occupancies of 0.718 (4) and 0.282 (4)] and two of the four perchlorate anions are disordered [occupancies of 0.735 (6):0.265 (6) and 0.637 (5):0.363 (5)]. There is extensive hydrogen bonding in the structure involving both N—H...O and C—H...O interactions, which link the histamine dications and perchlorate anions into a three-dimensional array.
