Crystal structure of (2E)-N-methyl-2-[(4-oxo-4H-chromen-3-yl)methylidene]hydrazinecarbothioamide

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 interactions, which generate R 2/2(10) loops.
