(3-Oxo-3H-benzo[f]chromen-1-yl)methyl piperidine-1-carbodithioate

Abstract

In the title compound, C20H19N O2S2,the 3Hbenzo-chromene ring system is nearly planar, with a maximum deviation of 0.036 (2) Å, and the piperidine ring adopts a chair conformation: the bond-angle sum for its N atom is 358.7°. The dihedral angle between the 3H-benzo[f]chromene ring and the piperidine ring is 89.07 (8)°. In the crystal, C—H⋯O hydrogen bonds lead to [010] C(6) chains and weak aromatic π–π inter­actions between the fused pyran ring and fused benzene ring of benzochromene [centroid–centroid distance = 3.652 (1) Å] are also observed.

Crystal structure ofS-(4-methylbenzyl) piperidinedithiocarbamate

“…The dihedral angle between the planar dithiocarbamate moiety S1/S2/N1/C6 and the planar p-tolyl frgament C7/C8/C9/C10/C11/C12/C13/C14 is 74.46 (10)°. The C7-S1-C6-S2 fragment adopts a cis conformation with the torsion angle of -6.6 (2)° comparable to previous literature (Kumar et al, 2013;Kotresh et al, 2012). The arrangement of the molecules in the crystal are dominated by the presence of the crystallographic 2-fold rotation axis.…”
