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 R22(14) loops. The dimers are reinforced by a pair of C—H...O interactions, which generate R22(10) loops.
