Abstract
The crystal structure of the title diprotonated diacetyltriethylenetetramine (DAT) perchorate salt, C10H24N4O22+·2ClO4−, can be described as a three-dimensional assembly of alternating layers consisting of diprotonated diacetyltriethylenetetramine (H2DAT)2+ strands along [100] and the anionic species ClO4−. The (H2DAT)2+ cations in the strands are connected via N—H...O hydrogen bonding between the acetyl groups and the amine groups of neighbouring (H2DAT)2+ cations. Layers of (H2DAT)2+ strands and perchlorate anions are connected by a network of hydrogen bonds between the NH and NH2 groups and the O atoms of the perchlorate anion. The asymmetric unit consits of one perchlorate anion in a general position, as well as of one cation that is located on a center of inversion.
