(E)-Methyl N′-(4-bromo­benzyl­idene)­hydrazinecarboxyl­ate at 123 K

The title compound, C(9)H(9)BrN(2)O(2), crystallizes with two independent but essentially identical mol­ecules in the asymmetric unit. Each mol­ecule adopts a trans configuration with respect to the C=N bond. In one of the mol­ecules, the dihedral angle between the benzene ring and the hydrazinecarboxylic acid plane is 24.9 (2)°, and that in the other mol­ecule is 16.1 (2)°. The mol­ecules are linked into a three-dimensional network via inter­molecular N—H⋯O, C—H⋯O, C—H⋯N and C—H⋯Br hydrogen bonds. An intramolecular N—H⋯O hydrogen bond is also present.
