Methyl (2Z)-((2Z)-2-{(2E)-[1-(4-methyl­phen­yl)ethyl­idene]hydrazinyl­idene}-4-oxo-3-phenyl-1,3-thia­zolidin-5-yl­idene)ethano­ate

The asymmetric unit of the title compound, C(21)H(19)N(3)O(3)S, 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.
