Sampayo, Luiz de Mello Vaz de published the artcileThe structure of 1,2-dibromotetramethylethane, Application In Synthesis of 594-81-0, the publication is Revista Portuguesa de Quimica (1961), 3(2), 57-66, database is CAplus.
It was demonstrated by x-ray diffraction that 1,2-dibromotetramethylethane crystallizes in the tetragonal system (symmetry group 4mm) with a 7.39 and c 8.14 A. The centered unit cell has Z = 2. The symmetry of the unit cell requires that the 2 mols. in it have their lowest axis of inertia along a 4-fold axis of the crystal. Under these circumstances the space group is of maximum symmetry I4/mmm, and the centers of the 2 mols. are at the origin and at the center of the unit cell. The observed intensities, to which the usual corrections including temperature and absorption corrections were applied, diverge slightly from the calculated ones. This was probably due to an imperfect determination of the crystal shape.
