6,7-Diphenyl-5-thia-7-aza­spiro­[2.6]nonan-8-one

H. P. Yennawar and L. J. Silverberg

Abstract: The asymmetric unit of the title compound, C19H19NOS, contains two independent mol­ecules (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 phenyl rings are 65.28 (8) and 60.31 (9)° for mol­ecules A and B, respectively. In the crystal, mol­ecules are linked by weak C-H...O inter­actions, resulting in a three-dimensional network.
