2,4-Dimethylanilinium perchlorate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2010
The crystal packing of the title compound, C(8)H(12)N(+)·ClO(4) (-), is stabilized by N-H⋯O hydrogen bonds, the protonated amine group acting as a hydrogen-bond donor with the perchlorate O atoms as acceptors. These connect neighbouring cations and anions, forming a two-dimensional network.
