Abstract
The asymmetric unit of the title compound, C21H19N3O3S, contains two independent molecules. In one molecule, the 1,3-thiazolidine ring forms dihedral angles of 86.19 (8) and 8.37 (8)° with the phenyl and benzene rings, respectively. The corresponding dihedral angles in the other molecule are 69.60 (7) and 14.08 (7)°. The dihedral angle between the phenyl and benzene rings is 84.70 (8)° in one molecule and 69.62 (8)° in the other. In the crystal, molecules pack in layers approximately parallel to (10-2). There are weak C—H⋯O hydrogen bonds within these layers. Further weak C—H⋯O hydrogen bonding occurs between the layers to form a three-dimensional network. A weak C—H⋯π interaction is also observed.
