title: (3-Oxo-3H-benzo[f]chromen-1-yl)methyl N,N-dimethyl-carbamodithio-ate.
abstract: In the title compound, C(17)H(15)NO(2)S(2), 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-dimethyl-carbamodithio-ate residue lies almost perpendicular to the pyran ring [dihedral angle = 85.15 (7)°]. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into C(10) chains propagating in [001].
