2-(4-Bromophenyl)-N-(pyrazin-2-yl)acetamide

Abstract

In the title compound, C12H10BrN3O, the dihedral angle between the mean planes of the 4-bromophenyl and pyrazin-2-yl rings is 54.6 (3)°. An intramolecular C—H...O hydrogen bond generates an S(6) graph-set motif. In the crystal, weak N—H...N hydrogen bonds link the molecules into chains along [100]. The chains are linked via C—H...N and C—H...O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane.
