چکیده
In the title compound, C(20)H(22)BrN(5)O(2)·2H(2)O, the Schiff base mol-ecule exists in an E conformation with respect to the acyclic C=N bond. An S(6) ring motif is formed via an intra-molecular O-H⋯N hydrogen bond. The dihedral angle between the imidazo[1,2-a]pyridine system and the benzene ring is 84.62 (5)°. In the crystal, N-H⋯O, O-H⋯O, O-H⋯N, C-H⋯O and C-H⋯Br hydrogen bonds link the mol-ecules into a three-dimensional network. The crystal packing is further stabilized by C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.5365 (7) Å].
