Abstract
2-Bromo-2, 3, 3-trimethylbutane gives a plastic crystal, which is optically isotropic and has a density of 1.31 g./cc. at 13°C. The X-ray data can be interpreted on the bases of a body-centered cubic lattice, having α=7.66 A with two molecules in the unit cell. The symmetry interpretation gives a structure of disordered orientation of molecules. It was found, by means of optical and differential thermal analysis methods, that there is a phase transition at about −114°C, below which the crystal is of a lower symmetry.
