Abstract
THE structures of 1:3:5-trichlorobenzene and of B.B.B-trichloroborazole have been analysed, and although not isomorphous they are in many respects very similar1,2. Both are nearly layer structures. The direction cosines of the molecular axes L (along one Cl-Cl direction), M, and N (normal to the ring) are as follows (at 20°C.): The intramolecular distances are: Both molecules are plane to within the limits of experimental error, and the rings are regular hexagons to within 0.04 A. in bond-lengths, and 2.5° in bond-angles.
