(2E)-3-{4-[(1H-1,3-Benzimidazol-2-yl)meth­oxy]-3-eth­oxy­phen­yl}-1-(4-bromo­phen­yl)prop-2-en-1-one monohydrate

In the title compound, C(25)H(21)BrN(2)O(3)·H(2)O, the benzimidazole fragment and the water mol­ecule of crystallization are each disordered over two sets of sites of equal occupancy. The dihedral angles between the least-squares planes of the benzimidazole and the 3-eth­oxy- and 4-bromo­benzene rings are 86.9 (6) and 85.1 (1)°, respectively in one disorder component. The crystal packing is stabilized by inter­molecular O—H⋯O, O—H⋯N and N—H⋯N hydrogen bonds, which link the mol­ecules into chains along the a axis.
