Schemes for the symmetry reduction (Bärnighausen tree) of the disordered crystal structure of thio­phosgene to facilitate quantum mechanical calculations. Left: Translationengleiche symmetry reduction leading to a model in the non-standard setting P1121/m (No. 11, standard setting P121/m1) with Z = 2. Right: Klassengleiche symmetry reduction leading to an enlarged unit cell in P63/m with Z = 6. Optimized coordinates from quantum chemical calculations are added in the bottom row.
