title: 7-Diethyl-amino-2-propyl-sulfan-yl-3-(1H-1,2,4-triazol-1-yl)-4H-thio-chromen-4-one.
abstract: In the title compound, C(18)H(22)N(4)OS(2), the six-membered rings are almost coplanar, showing a dihedral angle between the mean planes of 9.0 (4)°, while the triazol ring is nearly perpendicular to the thio-chromen-4-one unit, making an angle of 89.8 (4)°. In the crystal, C-H⋯N hydrogen bonds link the mol-ecules in a stacked arrangement along the c axis.
