N′-[(E)-4-Bromo­benzyl­idene]pyrazine-2-carbohydrazide

In the title compound, C(12)H(9)BrN(4)O, the N′-methyl­idene­pyrazine-2-carbohydrazide and 4-bromobenzene groups are oriented at a dihedral angle of 10.57 (7)°. The hydrazide N—H group is involved in intra­molecular N—H⋯N inter­action, which generates an S(5) motif. A short C—H⋯O inter­action is for...

description In the title compound, C(12)H(9)BrN(4)O, the N′-methyl­idene­pyrazine-2-carbohydrazide and 4-bromobenzene groups are oriented at a dihedral angle of 10.57 (7)°. The hydrazide N—H group is involved in intra­molecular N—H⋯N inter­action, which generates an S(5) motif. A short C—H⋯O inter­action is formed between the methyl­idene H atom and the carbonyl O atom. It connects mol­ecules into chains extending along [100]. In addition, mol­ecules are arranged into stacks extending along [010] via π–π inter­actions between pyrazine and benzene rings, with centroid–centroid distances of 3.837 (2) and 3.860 (2) Å.
