Crystal structure of (E)-2-[(4-chloro-2H-chromen-3-yl)methyl­idene]-N-cyclo­hexyl­hydrazinecarbo­thio­amide

In the title compound, C(17)H(20)ClN(3)OS, the mean plane of the central thio­urea core makes dihedral angles of 26.56 (9) and 47.62 (12)° with the mean planes of the chromene moiety and the cyclo­hexyl ring, respectively. The cyclo­hexyl ring adopts a chair conformation. The N–H atoms of the thio­urea unit adopt an anti conformation. The chromene group is positioned trans, whereas the cyclo­hexyl ring lies in the cis position to the thione S atom, with respect to the thio­urea C—N bond. In the crystal, mol­ecules are linked by N—H⋯S hydrogen bonds, forming inversion dimers enclosing R (2) (2)(8) ring motifs. The dimers are linked by C—H⋯Cl hydrogen bonds, enclosing R (6) (6)(44) ring motifs, forming sheets lying parallel to (010).
