: Hybrid dihydrogen arsenate salt with formula (C<sub>9</sub>H<sub>11</sub>N<sub>4</sub>)H<sub>2</sub>AsO<sub>4</sub> crystallizes in the monoclinic symmetry, with the non-centrosymmetric space group <i>P</i>2<sub>1</sub>. The asymmetric unit of the supramolecular structure is formed by one organic monoprotonated amine [C<sub>9</sub>H<sub>11</sub>N<sub>4</sub>]<sup>+</sup> and one inorganic anion [H<sub>2</sub>AsO<sub>4</sub>]<sup>−</sup>. In the crystal packing, anionic inorganic dimers are formed by two adjacent dihydrogen arsenate tetrahedron [H<sub>2</sub>AsO<sub>4</sub>]<sup>−</sup> interconnected by O–H···O hydrogen bonds ranging between 1.710 and 1.760 Å, while the organic molecules are bonded to these mineral dimers entities through N–H⋯O hydrogen bonds ranging between 1.799 and 2.129 Å. The association of organic and inorganic parts gives rise to a crystal structure with a fully supramolecular network. The inorganic and organic parts alternate along the crystallographic c axis.
