Summary
-
1.
We determined the space group and elementary cell parameters of tetrabromo-m-xylene and tetrabromo-o-xylene and the crystal structure of tetrabromo-m-xylene.
-
2.
The structures of tetrabromo-o-and tetrabromo-m-xylene are identical and are disordered due to the similarity of the radii of the substituents, which statistically occupy the same position in the cell.
-
3.
The tetrabromo-m-xylene molecule is planar with an accuracy of about ±0.02 A. The intermolecular radii were obtained from the shortest intermolecular distances.
