title: 2-(1H-Imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol monohydrate.
abstract: The asymmetric unit of the title compound, C(19)H(12)N(4)O·H(2)O, contains one organic molecule and one solvent water mol-ecule, which are connected by N-H⋯O and O-H⋯N hydrogen bonds. In addition, there is one intra-molecular O-H⋯N hydrogen bond. The organic mol-ecule is essentially planar (r.m.s. deviation for all non-H atoms = 0.028 Å).
