Abstract Results of the X-ray diffraction study of the crystal structure of (1S,3S)-1- tert- butyl-3-methyl-1-phenyl-1,3-dihydro-2-benzofuran and also its comparison with the crystal structure of (1S,3R)-1- tert- butyl-3-methyl-1-phenyl-1,3-dihydro-2-benzofuran that we analyzed previously by X-ray diffraction are presented. By means of the analysis of geometric and energy characteristics of active intermolecular atom-atom contacts substantial distinctions in these structures and the presence of almost the same geometric fragments are reveled in them.
