High- and low-temperature phases in isostructural 4-chloro-3-nitro­aniline and 4-iodo-3-nitro­aniline

Original language description

The structures of 4-chloro-3-nitro­aniline, C6H5ClN2O2, (I), and 4-iodo-3-nitro­aniline, C6H5IN2O2, (II), are isomorphs and both undergo continuous (second order) phase transitions at 237 and 200 K, respectively. The structures, as well as their phase transitions, have been studied by single-crystal X-ray diffraction, Raman spectroscopy and difference scanning calorimetry experiments. Both high-temperature phases (293 K) show disorder of the nitro substituents, which are inclined towards the benzene-ring planes at two different orientations. In the low-temperature phases (120 K), both inclination angles are well maintained, while the disorder is removed. Concomitantly, the b axis doubles with respect to the room-temperature cell.
