2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl pyrrolidine-1-carbodi-thio-ate.

ABSTRACT: There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds occur for one of the mol-ecules. Further C-H⋯O links involving both mol-ecules generate a three-dimensional network.
