RESUMO
In the title compound, C15H14ClNO2S2, the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.0133â (10)â Å. Three C atoms and their attached H atoms of the pyrrolidine ring are disordered [occupany ratio 0.874â (7):0.126â (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 89.45â (7)°. In the crystal, inversion dimers linked by pairs of C-Hâ¯S and C-Hâ¯O inter-actions generate R (2) 2(24) and R (2) 2(10) loops, respectively. Further C-Hâ¯O hydrogen bonds link the dimers into [100] chains. C-Hâ¯π inter-actions also occur and there is very weak π-π stacking [inter-planar spacing = 3.650â (5)â Å; centroid-centroid distance = 4.095â (7)â Å] between inversion-related chloro-benzene rings.
