چکیده
The title compound, C(9)H(9)BrN(2)O(2), crystallizes with two independent but essentially identical mol-ecules in the asymmetric unit. Each mol-ecule adopts a trans configuration with respect to the C=N bond. In one of the mol-ecules, the dihedral angle between the benzene ring and the hydrazinecarboxylic acid plane is 24.9 (2)°, and that in the other mol-ecule is 16.1 (2)°. The mol-ecules are linked into a three-dimensional network via inter-molecular 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.

In the title compound, C12H9BrN4O, the N'-methyl-idene-pyrazine-2-carbohydrazide and 4-bromobenzene groups are oriented at a dihedral angle of 10.57 (7)°. The hydrazide N-H group is involved in intra-molecular N-H⋯N inter-action, which generates an S(5) motif. A short C-H⋯O inter-action is formed between the methyl-idene H atom and the carbonyl O atom. It connects mol-ecules into chains extendi...
