Abstract

X-ray and neutron diffraction studies of 2-amino-5-chloropyridine, C5H5ClN2, were previously carried out at room temperature [Kvick & Backéus (1974). Acta Cryst. B30, 474–480; Kvick, Thomas & Koetzle (1976). Acta Cryst. B32, 224–231]. This report is a redetermination of the crystal structure at 100?K. As previously observed, molecules form centrosymmetric dimers via two N—H...N hydrogen bonds. In addition, C—H...π interactions are generated from molecules related by c-glide transformations, which form extended two-dimensional aggregation in the bc plane.
