چکیده
The benzohydrazide mol-ecule of the title compound, C(14)H(10)BrClN(2)O(5)·CH(3)OH, is non-planar, the two aromatic rings at either side of the -C(=O)-NH-N=CH- unit being twisted by 5.9 (1)°. The benzohydrazide mol-ecule is linked to the solvent mol-ecule by an O-H⋯O hydrogen bond. Mol-ecules are connected by further O-H⋯O hydrogen bonds and an N-H⋯O link into a two-dimensional array.
