Methyl (2Z)-2-{(2Z)-3-[(cyclo­pentyl­idene)amino]-4-oxo-2-phenyl­imino-1,3-thia­zol­idin-5-yl­idene}acetate

In the title compound, C(17)H(17)N(3)O(3)S, the thia­zole ring is nearly planar [maximum deviation = 0.015 (1) Å for the ring N atom] and the cyclo­pentane ring has a twist conformation. The mol­ecular conformation is stabilized by a hypervalent inter­action between the S atom and the ester group carbonyl O atom, with an S⋯O distance of 2.7931 (10) Å. In the crystal, C—H⋯O inter­actions generate chains of mol­ecules propagating along [110] and π–π stacking inter­actions [centroid–centroid distance = 3.4677 (7) Å] between the thia­zole rings organize these chains into (001) layers.
