Beschreibungen/Notizen

• The title compound, C12H10BrN3O2S, exists in an E configuration with respect to the C=N bond. The approximately planar 2H-chromene ring system [maximum deviation = 0.059 (1) Å] is inclined at a dihedral angle of 17.50 (5)° with respect to the mean plane through the thiosemicarbazide unit and an intramolecular N—H...N hydrogen bond generates an S(5) ring. In the crystal structure, adjacent molecules are linked by N—H...S hydrogen bonds, forming [010] chains built up from R22(8) loops, such that each S atom accepts two such bonds. These chains are further interconnected into sheets parallel to the ab plane via short Br...O interactions [3.0732 (13) Å] and a π–π aromatic stacking interaction [3.7870 (8) Å] is also observed.
