چکیده
In the title compound, C(13)H(12)N(4)O(2), all the non-H atoms lie on a crystallographic mirror plane and an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring; the conformation about the imine bond [1.280 (3) Å] is E. In the crystal, mol-ecules assemble into a two-dimensional array via C-H⋯O(carbon-yl) and C-H⋯N(pyrazine) contacts. Layers stack along the b-axis direction via weak π-π inter-actions between pyrazine rings [ring centroid distance = 3.8028 (8) Å].

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

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 th...
