Description
Summary:The title compound, C11H9N3O2S, crystallizes with two independent molecules in the asymmetric unit. The central thiourea core makes dihedral angles of −3.3 (3) and 0.6 (3)° with the furan carbonyl groups in each molecule, whereas the pyridine ring is inclined by 4.63 (2) and 11.28 (7)°, respectively. The trans–cis geometry of the thiourea fragment is stabilized by an intramolecular N—H...N hydrogen bond between the H atom of the cis-thioamide group and the pyridine N atom. In the crystal structure, intermolecular bifurcated N—H...S and N—H...O hydrogen bonds form centrosymmetric tetramers extending along the b axis.
