title: 1-Bromo-2,7-di-tert-butyl-pyrene.
abstract: In the title mol-ecule, C(24)H(25)Br, one of two tert-butyl groups is rotationally disordered between two orientations in a 0.59 (3):0.41 (3) ratio. The crystal packing exhibits no π-π inter-actions; however, relatively short inter-molecular Br⋯Br contacts of 3.654 (1) Å are observed.
