A catemeric crystal structure of cyheptamide undergoes a transformation in the solid-state upon heating to produce dimer-based form whose has been determined from laboratory X-ray powder diffraction (XRPD) data, thereby providing first conclusive evidence carbamazepine analogue crystallising both hydrogen bonded motifs.
