title: Crystal structure of (2E)-N-methyl-2-[(4-oxo-4H-chromen-3-yl)methyl-idene]hydrazine-carbo-thio-amide.
abstract: In the title compound, C12H11N3O2S, the dihedral angle between the 4H-chromen-4-one ring system and the -CH=N-NH-CS-NH- unit is 6.22 (1)°. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(14) loops. The dimers are reinforced by a pair of C-H⋯O inter-actions, which generate R 2 (2)(10) loops.
