(3-Oxo-3H-benzo[f]chromen-1-yl)methylN,N-dimethylcarbamodithioate

Abstract

In the title compound, C17H15NO2S2, the 3H-benzo[f]chromene ring system is distinctly twisted; the dihedral angle between the pyran ring and its opposite benzene ring is 9.11 (8)°. The N,N-dimethyl­carbamodithio­ate residue lies almost perpendicular to the pyran ring [dihedral angle = 85.15 (7)°]. In the crystal, weak C—H⋯O hydrogen bonds link the mol­ecules into C(10) chains propagating in [001].
