An Implementation and Experimental

disorder in main residue; R factor = 0.044; wR factor = 0.119; data-to-parameter ratio = 12.4. In the title compound, C24H34O3S, the dihedral angle between the benzene rings is 84.62 (8). In the crystal, intermolecular C—H O hydrogen bonds link molecules into zigzag chains running parallel to the c axis. The C atoms of two isopropyl groups are disordered over two sets of sites with occupancy ratios of 0.858 (9):0.142 (9) and 0.61 (5):0.39 (5).
