Chemical preparation, crystal structure, NMR spectroscopy and thermal investigations of the 4-dimethylaminopyridinium dihydrogenmonophosphate (C7H11N2)H2PO4 are studied. This compound crystallizes in the triclinic system, with the space group P $$ \mathop 1\limits^-} $$ and the following parameters: a = 7.8046(3) Å, b = 8.0826(3) Å, c = 8.4262(3) Å, α = 98.497(3)°, β = 104.689(3)°, γ = 99.428(3)°, V = 497.14(3) Å3, Z = 2. The structural arrangement can be described as inorganic chains, $$ [\textH}}_ 2} \textPO}}_ 4} ]_\textn}}^\textn}} - }} $$ , parallel to the a-direction, the organic cations are linked to these chains by hydrogen bonds N–H···O to form a three-dimensional infinite network.
