(7,8-Dimethyl-2-oxo-2H-chromen-4-yl)methyl piperidine-1-carbodi-thio-ate

摘要

In the title compound, C 18 H 21 NO 2 S 2 , the 2 H -chromene ring systems is nearly planar, with a maximum deviation of 0.023?(2)??. The coumarin unit makes a dihedral angle of 60.54?(8)° with the piperidine ring, which adopts a chair conformation. The carbodi-thio-ate group is present in a synperiplanar conformation with respect to the piperidine ring, as indicated by the torsion angle of ?4.7?(2)°. A short intra-molecular C—H?S conatct generates an S (5) ring. No directional inter-actions beyond van der Waals contacts could be identified in the crystal.
