3-Carbamoylquinoxalin-1-ium chloride

J. K. Harper, G. Strobel and A. M. Arif

Abstract: The title compound, C9H8N3O+·Cl-, was isolated from a liquid culture of streptomyces sp. In the cation, the ring system makes a dihedral angle of 0.2 (2)° with the amide group. The protonation creating the cation occurs at ome of the N atoms in the quinoxaline ring system. In the crystal, the ions are linked through N-H...O and N-H...Cl hydrogen bonds, forming a two-dimensional network parallel to (10\overline{3}).
