Abstract
The title compound, C(11)H(9)N(3)O(2)S, crystallizes with two independent mol-ecules in the asymmetric unit. The central thio-urea core makes dihedral angles of -3.3 (3) and 0.6 (3)° with the furan carbonyl groups in each mol-ecule, whereas the pyridine ring is inclined by 4.63 (2) and 11.28 (7)°, respectively. The trans-cis geometry of the thio-urea fragment is stabilized by an intra-molecular N-H⋯N hydrogen bond between the H atom of the cis-thio-amide group and the pyridine N atom. In the crystal structure, inter-molecular bifurcated N-H⋯S and N-H⋯O hydrogen bonds form centrosymmetric tetra-mers extending along the b axis.
