N-(2-Chloro­eth­yl)pyrazine-2-carboxamide

In the title mol­ecule, C(7)H(8)ClN(3)O, 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...

Sumario:In the title mol­ecule, C(7)H(8)ClN(3)O, 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—H⋯N hydrogen bonds leads to the formation of a C(6) supra­molecular chain along the b axis. The carbonyl-O atom accepts two C—H⋯O inter­actions. These, plus Cl⋯Cl short contacts [3.3653 (6) Å], consolidate the packing of the chains in the crystal.
