In the title compound, C17H19NO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.0383 (28) Å, and the piperidine ring adopts a chair conformation. The 2H-chromene ring makes dihedral angles of 32.89 (16) and 67.33 (8)°, respectively, with the mean planes of the piperidine ring and the carbodithioate group. In the crystal, C—H⋯O and weak C—H⋯S hydrogen bonds link the molecules into chains along [001]. The also features C—H⋯π and π–π interactions, with a centroid–centroid distance of 3.7097 (17) Å.

The title compound compound was prepared according to a reported method (Kumar et al., 2013). Colourless needles of the title compound were grown from a mixed solution of EtOH/CHCl3 (v/v = 1/1) by slow evaporation at room temperature. Yield: 80%, m.p. 420 K.
All H atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H, C—H = 0.97 Å for methylene H and C—H = 0.96 Å for methyl H,and refined using a riding model with Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for all other H.
Coumarins and their derivatives play an important role in the agricultural and pharmaceutical industries (Stiefel et al., 1995). They are widely present in higher plants such as Rutaceae, Apiaceae, Asteraceae, Leguminosae, Thymelaeaceae, and they also occur as animal and microbial metabolites (Murray et al., 1982). Most of them show a wide spectrum of pharmacological effects, including antimicrobial (Khan et al., 2004), anti-arrhythmic, antiosteoporosis, anti-HIV, and antitumor activities (Kawaii et al., 2001; Yu et al., 2003). Accordingly, many reports have described various structures and biological evaluations of numerous coumarin analogs newly synthesized or isolated from plants.
Sulfur containing molecules are currently under study as chemoprotectants in chemotherapy. Organic substances with a dithio π [Cg(3) (C9–C15)] and [Cg(1) (O3/C6–C10)]π–π [Cg(3) (C9–C15)] interactions, with centroid–centroid distances of 3.7081 (15) Å that further stabilize the crystal packing, Figure 2.
have been widely used in industry as rodent repellents, vulcanization additives in rubber manufacturing, additives in lubricants, and in agriculture as fungicides on almond trees, stone fruits, and vegetables. Among the various sulfur ligands being examined currently, dithiocarbamates have a special significance owing to their many uses, e.g. in analytical determinations, as arrestors of human immunodeficiency virus infections such as AIDS, in pharmaceutical products, in agriculture as pesticides and fungicides, and as high-pressure lubricants (D'hooghe & de Kime, 2006; Thorn & Ludwig, 1962; Cao et al., 2005). One molecule of (7-methyl-2-oxo-2H-chromen-4-yl)methylpiperidine-1-carbodithioate is shown in Fig. 1. The 2Hchromene ring system (O3/C6–C13/C15) is essentially planar, with a maximum deviation of 0.0383 (28) Å for atom C10 and the piperidine (N5/C18–C22) ring adopts a chair conformation. The dihedral angle of the 2H-chromene (O3/C6–C13/C15) ring with the piperidine (N5/C18–C22) ring and carbodithioate group are 32.89 (16)° and 67.33 (8)°, respectively. In addition, intermolecular C—H···O and weak C—H···S hydrogen bonds (Table 1) link the components into chains along [001]. The also features C—H···For biological applications of

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

Coumarins and their derivatives play an important role in the agricultural and pharmaceutical industries (Stiefel et al., 1995). They are widely present in higher plants such as Rutaceae, Apiaceae, Asteraceae, Leguminosae, Thymelaeaceae, and they also occur as animal and microbial metabolites (Murray et al., 1982). Most of them show a wide spectrum of pharmacological effects, including antimicrobial (Khan et al., 2004), anti-arrhythmic, antiosteoporosis, anti-HIV, and antitumor activities (Kawaii et al., 2001; Yu et al., 2003). Accordingly, many reports have described various structures and biological evaluations of numerous coumarin analogs newly synthesized or isolated from plants.
Sulfur containing molecules are currently under study as chemoprotectants in chemotherapy. Organic substances with a dithio functional group have been widely used in industry as rodent repellents, vulcanization additives in rubber manufacturing, additives in lubricants, and in agriculture as fungicides on almond trees, stone fruits, and vegetables. Among the various sulfur ligands being examined currently, dithiocarbamates have a special significance owing to their many uses, e.g. in analytical determinations, as arrestors of human immunodeficiency virus infections such as AIDS, in pharmaceutical products, in agriculture as pesticides and fungicides, and as high-pressure lubricants (D'hooghe & de Kime, 2006; Thorn & Ludwig, 1962; Cao et al., 2005). One molecule of (7-methyl-2-oxo-2H-chromen-4-yl)methylpiperidine-1-carbodithioate is shown in Fig. 1. The 2Hchromene ring system (O3/C6–C13/C15) is essentially planar, with a maximum deviation of 0.0383 (28) Å for atom C10 and the piperidine (N5/C18–C22) ring adopts a chair conformation. The dihedral angle of the 2H-chromene (O3/C6–C13/C15) ring with the piperidine (N5/C18–C22) ring and carbodithioate group are 32.89 (16)° and 67.33 (8)°, respectively. In addition, intermolecular C—H···O and weak C—H···S hydrogen bonds (Table 1) link the components into chains along [001]. The crystal structure also features C—H···π [Cg(3) (C9–C15)] and [Cg(1) (O3/C6–C10)]π–π [Cg(3) (C9–C15)] interactions, with centroid–centroid distances of 3.7081 (15) Å that further stabilize the crystal packing, Figure 2.
