6,7-Diphenyl-5-thia-7-aza-spiro-[2.6]nonan-8-one 5,5-dioxide.

ABSTRACT: The racemic mixture of the title compound, C₁₉H₁₉NO₃S, crystallizes in space group P with two homochiral mol-ecules in each asymmetric unit. The seven-membered ring in both mol-ecules is in a pucker-chair conformation. The extended structure exhibits C-H⋯O hydrogen bonds, of which two connect crystallographically independent mol-ecules to generate a chain propagating along the b-axis direction. One C-H grouping of the cyclo-propyl ring is in close contact with the phenyl ring of the neighboring independent mol-ecule in C-H⋯π type inter-actions with carbon atom-ring-centroid distances of 3.544 (5) and 3.596 (4) Å. Other inter-actions are of the parallel-reciprocal type, with the chiral carbon atom of one mol-ecule donating a proton to an oxygen
