2-Methyl-anilinium dihydrogen phosphate-phospho-ric acid (1/1).

In the title compound, C(7)H(10)N(+)·H(2)PO(4) (-)·H(3)PO(4), there is a clear distinction between the P-O/P=O and P-OH bond lengths. In the crystal, the H(2)PO(4) (-) anions and H(3)PO(4) mol-ecules are linked by O-H⋯O hydrogen bonds, leading to layers propagating in the bc plane. The organic cations are located between these layers and inter-act with them by way of N-H⋯O hydrogen bonds.
