چکیده
The title compound, C(9)H(8)Br(2)N(2)O(3), is planar (r.m.s. deviation = 0.030 Å) with the exception of the terminal methyl group which lies out of the plane [1.219 (3) Å]. The conformation about the C=N double bond [1.268 (3) Å] is E. An intra-molecular N-H⋯N hydrogen bond occurs. Linear supra-molecular chains along the b axis mediated by O-H⋯O hydrogen-bonding inter-actions feature in the crystal structure. These chains are also stabilized by weak C-H⋯N contacts.
