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
).
For a description of the bioactivity and mode of action of compounds containing the quinoxaline moiety, see: Bailly et al. (1999
); May et al. (2004
); Mollegaard et al. (2000
); Waring (1993
). For crystal structures of the molecules triostin A, echinomycin and their derivatives, which all contain two quinoxalines, see: Hossain et al. (1982

, 1995
