2-[(Quinolin-8-yloxy)methyl]-1H-benzimidazole monohydrate

In the title hydrate, C17H13N3O·H2O, the dihedral angle between the quinoline and benzimidazole ring systems is 6.22 (7)°. The water molecule is linked to the main molecule by N—H...O and O—H...N hydrogen bonds. Further O—H...N hydrogen bonds link the organic molecules into C(6) chains running parallel to the b axis
