title: N'-[(E)-2,6-Dichloro-benzyl-idene]pyrazine-2-carbohydrazide.
abstract: The title compound, C(12)H(8)Cl(2)N(4)O, is non-planar, the dihedral angle formed between the pendant pyrazine and benzene rings being 12.55 (11)°. An intra-molecular N-H⋯N hydrogen bond occurs. The amide groups self-associate via N-H⋯O hydrogen bonding, forming supra-molecular chains with base vector [101], which are stabilized by C-H⋯O contacts. C-H⋯N inter-actions are formed orthogonal to the chains.
