Physical Properties and Crystal Structure of 1,1,1,2-Tetrachloro-2-methylpropane

Abstract 1,1,1,2-Tetrachloro-2-methylpropane is cubic at room temperatures. X-ray date may be interpreted on the basis of a body-centered packing of molecules in disorder, orientational or rotational. The cube edge of the unit containing two molecules is a=7.4Å. The crystal undergoes transition at about −62.2°C, when cooled, and at −39.7°C,when heated starting at a lower temperature.
