چکیده
In the title compound, C(25)H(21)BrN(2)O(3)·H(2)O, the benzimidazole fragment and the water mol-ecule 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-eth-oxy- and 4-bromo-benzene rings are 86.9 (6) and 85.1 (1)°, respectively in one disorder component. The crystal packing is stabilized by inter-molecular O-H⋯O, O-H⋯N and N-H⋯N hydrogen bonds, which link the mol-ecules into chains along the a axis.
