X-ray and neutron diffraction studies of 2-amino-5-chloropyridine, C 5 H 5 ClN 2 , were previously carried out at room temperature [Kvick & Backe ´us (1974). Acta Cryst. B30, 474-480;Kvick, Thomas & Koetzle (1976). Acta Cryst. B32, [224][225][226][227][228][229][230][231]. This report is a redetermi
ÁBr À is, to our knowledge, the ®rst reported example of a simple salt of cationic mono-Nprotonated 1,10-phenanthroline-5,6-dione. All of the atoms lie on a crystallographic mirror plane and the cation is therefore totally planar. As a consequence, the compound has a well de®ned layer structure in w
The crystal structure of the title compound, C~3~H~3~NOS~2~, has been redetermined at 173 K. The geometric parameters show a significant improvement in precision from the orginal determination [Van der Helm, Lessor & Merritt (1962). __Acta Cryst__. **15**, 1227–1232], where the data were measured us
