title: Methyl (2Z)-((2Z)-2-{(2E)-[1-(4-methyl-phen-yl)ethyl-idene]hydrazinyl-idene}-4-oxo-3-phenyl-1,3-thia-zolidin-5-yl-idene)ethano-ate.
abstract: The asymmetric unit of the title compound, C21H19N3O3S, contains two independent mol-ecules. In one mol-ecule, the 1,3-thia-zolidine 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 mol-ecule are 69.60 (7) and 14.08 (7)°. The dihedral angle between the phenyl and benzene rings is 84.70 (8)° in one mol-ecule and 69.62 (8)° in the other. In the crystal, mol-ecules 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 inter-action is also observed.
