(7-Chloro-2-oxo-2H-chromen-4-yl)methyl pyrrolidine-1-carbodithioate

Abstract

In the title compound, C15H14ClNO2S2, the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.0133 (10) Å. Three C atoms and their attached H atoms of the pyrrolidine ring are disordered [occupany ratio 0.874 (7):0.126 (7)] with both disorder components adopting a twisted conformation. The dihedral angle between the 2H-chromene ring system and the major occupancy component of the pyrrolidine ring is 89.45 (7)°. In the crystal, inversion dimers linked by pairs of C—H...S and C—H...O interactions generate R22(24) and R22(10) loops, respectively. Further C—H...O hydrogen bonds link the dimers into [100] chains. C—H...π interactions also occur and there is very weak π–π stacking [interplanar spacing = 3.650 (5) Å; centroid–centroid distance = 4.095 (7) Å] between inversion-related chlorobenzene rings.
