An unrestrained (left) and restrained (right) disordered tertiary butyl group. An unrestrained disordered tertiary butyl group with the hydrogen atoms and rest of the structure omitted for clarity (left). In this case, the two disordered components are shown with red and green bonds and atoms on opposite sides are restrained using asymmetric similarity restraints (right). Thus, C70 is restrained to be similar to C370 etc
