Abstract:
The title compound, C(15)H(12)BrN(3)O(4), displays a trans conformation with respect to the C=N double bond. The central atoms around the C=N double bond are not coplanar, in contrast to the aromatic rings, which exhibit a dihedral angle of 1.80 (4)° between their mean planes. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are connected via inter-molecular N-H⋯O hydrogen bonding into chains along the a axis.
