Carbamazepine forms a 1:1 solvate with trifluoro-acetic acid (systematic name: 5H-dibenzo[b,f]azepine-5-carboxamide trifluoro-acetic acid solvate), C15H12N2O·C2HF3O2. The compound crystallizes with one mol-ecule of carbamazepine and one of trifluoro-acetic acid in the asymmetric unit to form an R 2 2(8) motif. The solvent mol-ecule is disordered over two sites, with site-occupancy factors 0.53 (1) and 0.47 (1). © International Union of Crystallography 2007.
