Crystal structure of (S)-5-chloro-N-({2-oxo-3-[4-(3-oxomorpholin-4-yl)phen-yl]oxazolidin-5-yl}meth-yl)thio-phene-2-carboxamide.

The asymmetric unit of the crystal of the title compound (common name rivaroxaban), C19H18ClN3O5, contains two rivaroxaban mol­ecules with different conformations; the C—C—N—C torsion angles between the oxazolidine and thio­phene rings are −171.1 (7) and −106.8 (9)° in the two independent mol­ecules. In the crystal, classical N—H⋯O hydrogen bonds and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional supra­molecular architecture.
