Abstract
In the title molecule, C7H8ClN3O, the pyrazine and amide groups are almost co-planar [N-C-C-N torsion angle = -2.4 (2) °], a conformation stabilized by an intramolecular N-H
N hydrogen bond. The chloroethyl group lies out of the plane [N-C-C-Cl = -65.06 (17) °]. In the crystal, the presence of N-HN hydrogen bonds leads to the formation of a C(6) supramolecular chain along the b axis. The carbonyl-O atom accepts two C-HO interactions. These, plus ClCl short contacts [3.3653 (6) Å], consolidate the packing of the chains in the crystal.
