Abstract: The asymmetric unit of the title compound, C₁₃H₁₁N₃O₅S, contains two independent molecules, which are linked by a pair of intermolecular N-HS hydrogen bonds, forming an R₂²(8) ring motif. The central thiourea core forms dihedral angles of 3.02 (12) and 14.00 (10)° with the essentially planar furoyl groups [maximum deviations = 0.030 (2) and 0.057 (2) Å] in the two molecules and dihedral angles of 2.43 (13) and 8.03 (12)° with the benzene rings. The dihedral angles between the furoyl and benzene rings in the two molecules are 3.97 (10) and 5.98 (9)°. The trans-cis geometry of the thiourea group is stabilized by three intramolecular N-HO hydrogen bonds involving carbonyl and methoxy O atoms with the H atom of the cis-thioamide group and between furan O atom and the other thioamide H atom. There is also a weak intramolecular C-HS interaction in each molecule.
