N2 - The title compounds, (C8H20N)[H2AsO4][H3AsO4](2), (I), and (C6H14N2)[H2AsO4](2)[H3AsO4], (II), are unusual salts containing organic cations, dihydrogenarsenate anions and neutral arsenic acid molecules. In (I), the dihydrogenarsenate anion lies across a twofold rotation axis in the space group C2/c, while the cation is disordered across a centre of inversion. The [H2AsO4]. and H3AsO4 species interact by way of O-H center dot center dot center dot O hydrogen bonds, leading to sheets and a three-dimensional network for (I) and (II), respectively.
