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.eninfo:eu-repo/semantics/openAccessArticle10.1107/S16005368120437722-s2.0-84870916284+23284520Q3O321368WOS:000421552000210N/A
