Abstract
The title compound, C12H7N2O2+·Cl−, is isostructural with its bromide analogue. The compound exhibits a layered structure in which all atoms lie on a crystallographic mirror plane. N+—H...Cl− hydrogen bonds, C—H...O and C—H...Cl− contacts are formed within each layer. The perpendicular separation between the layers is 3.141 (1) Å.
