Herring-bone pi-pi interactions in trans-2,6-diphenyl-2,3,5,6-tetrahydrothiapyran-4-one.
The structure of the title compound, C(17)H(16)OS, is primarily stabilized by T-shaped and parallel-displaced aromatic clusters. The distances between the centroids of the aromatic pairs are in the range 4.34-5.30 A. In the crystal packing, the molecules dimerize by means of pi-pi interactions of both face-to-face and edge-to-face types, and the aromatic rings associate in a cyclic edge-to-face tetrameric arrangement of the herring-bone type. These herring-bone interactions appear to insulate hydrogen-bond interactions in the crystal structure.
