2-Oxo-2,3-dihydro-1H-imidazo[1,2-a]pyridinium iodide
Abstract
In the title compound, C7H7N2O+·I−, the carbonyl C and O atoms of the cation and the iodide ion are situated on mirror planes. The mean plane of the imidazo[1,2-d]pyridinium cation is perpendicular to the mirror plane as a consequence of the disorder of the cation over two opposite orientations of equal occupancy. In the crystal, N—H...I interactions are present.
