2-(4-Fluoro-phen-yl)-1-phenyl-1H-imidazo[4,5-f][1,10]phenanthroline monohydrate

In the title compound, C(25)H(15)FN(4)·H(2)O, the fused ring system is essentially planar [maximum deviation of 0.0822 (14) Å]. The imidazole ring makes dihedral angles of 76.83 (7) and 32.22 (7)° with the phenyl group attached to nitro-gen and the fluoro-benzene group to carbon, respectively. The dihedral angle between the two phenyl rings is 72.13 (7)°. Inter-molecular O-H⋯N, O-H⋯F, C-H⋯F, C-H⋯O and C-H⋯N hydrogen bonds are found in the crystal structure.
