چکیده
The asymmetric unit of the title compound, C(15)H(13)BrN(2)O(3)·0.5CH(3)OH, contains two Schiff base mol-ecules and a methanol mol-ecule of crystallization. The dihedral angles between the benzene rings in the two mol-ecules are 23.8 (2) and 18.6 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional network.
