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

Abstract

In the title compound, C17H17N3O3S, 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.
