Figure 2
Displacement ellipsoid plots for 1,2,4,5-tetra­bromo­benzene mol­ecules obtained with different data-treatment procedures. Carbon atoms for structure refinements (g), (h) and (i) were refined using an isotropic approximation. Cubes show atoms with negative thermal parameters. Refinements marked V are preferable for publication; those marked W are publishable but not always preferable, and those marked X are not acceptable for publication (incorrect).
