What is Forced twin-chair conformation in 7-benzoyl- and 7-phenylacetyl- r -2, c -4, t -6, t -8-tetraphenyl-3-thia-7-azabicyclo[3.3.1]nonanes with 1,3-diaxial phenyl groups in the piperidine ring: single- and double-layered supramolecular sheets built from C—H...O and C—H...π(arene) hydrogen bonds about?
The crystal structures of 7-benzoyl-r-2,c-4,t-6,t-8-tetraphenyl-3-thia-7-azabicyclo[3.3.1]nonane, C(38)H(33)NOS, (I), and r-2,c-4,t-6,t-8-tetraphenyl-7-phenylacetyl-3-thia-7-azabicyclo[3.3.1]nonane [systematic name: 2-phenyl-1-(r-2,c-4,t-6,t-8-tetraphenyl-3-thia-7-azabicyclo[3.3.1]nonan-7-yl)ethanone], C(39)H(35)NOS, (II), both reveal a forced twin-chair conformation with the 1,3-diaxial phenyl groups in the piperidine ring, and flattening at the N-atom end of the piperidine ring of the bicyclic system. In the crystal structure of (I), molecules are linked into sheets by a combination of two weak C-H...O and one C-H...pi(arene) hydrogen bond, while in the crystal structure of (II), the molecules extend into double-layered sheets assisted by three C-H...pi(arene) hydrogen bonds.
