چکیده
In the title compound, C(18)H(18)BrClN(2)O(2)·C(2)H(6)O, the hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond, which influences the conformation of the Shiff base mol-ecule, where the two aromatic rings form a dihedral angle of 21.67 (8)°. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link two Shiff base mol-ecules and two solvent mol-ecules into a centrosymmetric heterotetra-mer. Weak inter-molecular C-H⋯O inter-actions link further tetra-mers related by translation along the a axis into chains.
