Özet

The title compound, C16H19N3O4S, is almost planar, with a dihedral angle of 2.88 (9)degrees between the mean planes of the benzene and thiazole rings. The molecule adopts an E conformation about the two C = N bonds, with a C-N-N- C torsion angle of -177.01 (11)degrees. An intramolecular CH center dot center dot center dot O hydrogen bond exists between a thiazole methyl group and the formic acid ethyl ester carbonyl O atom. In the crystal, molecules are linked by O-H center dot center dot center dot O hydrogen bonds, forming chains propagating along [210]. The chains are linked via CH center dot center dot center dot O hydrogen bonds with R-2(2) (12) ring motifs, forming sheets lying parallel to (122). The sheets are further linked through out-of-plane C-H center dot center dot center dot N hydrogen bonds with R-2(2) (12) ring motifs and C-H center dot center dot center dot pi nteractions, forming an interesting three-dimensional supramolecular architecture.
