The geometric parameters of the title compound, C 15 H 13 BrN 2 O 3 , are in the usual ranges. The C N double bond is trans configured. The C N-N-CO-group itself is planar, with an r.m.s. deviation of 0.044 A ˚, and makes a dihedral angle of 10.73 (19) with the hydroxyphenyl ring, but forms a dihedr
