title: 2-Cyano-anilinium dihydrogen phosphate.
abstract: In the cation of the title compound, C(7)H(7)N(2) (+)·H(2)PO(4) (-), the nitrile group and the benzene ring are almost coplanar (r.m.s. deviation = 0.0035 Å). The cations and anions are connected by inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, together with π-π inter-actions [centroid-centroid distance = 3.8131 (9) Å], forming a three-dimensional network.
