Abstract: The title compound, C₁₄H₁₁BrN₂O₅·2H₂O, crystallizes as hydrogen-bonded sheets. The 2-hydroxy group on the benzylidene group forms an intramolecular hydrogen bond to the N atom of the C=N double bond. The amino N atom is a hydrogen-bond donor to a water molecule. The hydroxy group on the benzohydrazide group is a hydrogen-bond donor to one acceptor site, whereas each water molecule is a hydrogen-bond donor to two acceptor sites.
