On the crystal structures of two inclusion compounds of tris(5-acetyl-3-thienyl)methane


The crystal structures of the ethanol and the ethyl acetate inclusion compounds of TATM, CH(C_6-H_5OS)_3, were originally reported in space group P1, with two independent TATM molecules and one solvent molecule in the unit cell. However, the pairs of TATM molecules are closely related by centers of symmetry and the structures are better described in space group P1. Refinements in P1 led to lower e.s.d. 's and R values and to much more reasonable bond lengths, angles and U_(ij)'s for the TATM molecules; however, the solvent molecules are disordered and can be described no better in P1 than they were in P1.
