2-Phenyl-anilinium dihydrogen phosphate.

In the crystal structure of the title compound, C(12)H(12)N(+)·H(2)PO(4) (-), the dihydrogen phosphate anions and the 2-phenyl-anilinium cations are associated via O-H⋯O and N-H⋯O hydrogen bonds so as to build inorganic layers around the x = 1/2 plane. The organic entities are anchored between these layers through C-H⋯O hydrogen bonds, forming a three-dimensional infinite network. The dihedral angle between the aromatic rings is 44.7 (4)°.
