Yennawar, Hemant P. published the artcile6,7-Diphenyl-5-thia-7-azaspiro[2.6]nonan-8-one, Category: quinuclidine, the publication is Acta Crystallographica, Section E: Structure Reports Online (2013), 69(11), o1659, database is CAplus and MEDLINE.
The asym. unit of the title compound, C19H19NOS, contains two independent mols. (A and B), in both of which the 1,3-thiazepan-4-one ring adopts a chair-type conformation. The dihedral angles between the two Ph rings are 65.28(8) and 60.31(9)° for mols. A and B, resp. In the crystal, mols. are linked by weak C-H···O interactions, resulting in a three-dimensional network. Crystallog. data and at. coordinates are given.
