4-Ethoxy-anilinium hexa-fluoro-phosphate monohydrate.

In the crystal of the title compound, C(8)H(12)NO(+)·PF(6) (-)·H(2)O, inter-molecular N-H⋯F, N-H⋯O and O-H⋯F hydrogen bonds link the mol-ecules into chains along the c axis and C-H⋯π contacts further stabilize the structure. The F atoms of one of the hexa-fluoro-phosphate anions are disordered over two sets of sites with site-occupancy factors of 0.27†(3) and 0.73†(3).
