N'-[(E)-4-Bromo-benzyl-idene]pyrazine-2-carbohydrazide.

ABSTRACT: 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 extending along [100]. In addition, mol-ecules are arranged into stacks extending along [010] via ?-? inter-actions between pyrazine and benzene rings, with centroid-centroid distances of 3.837?(2) and 3.860?(2)?Å.

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.
