2,2,4,4-Tetramethyl-1,5-diphenyl-6,7,8-trioxa-3-thiabicyclo
The structure of the title ozonide, C(20)H(22)O(3)S, produced without the use of ozone, has been defined at 123 (1) K. In the triclinic crystal, the molecule has symmetry close to C(s), and its ozonide and 1,4-oxathiane rings have envelope and chair conformations, respectively. The ozonide unit has an O-O bond length of 1.4721 (12) A and a C-O-O-C torsion angle of -1.45 (12) degrees.
