Crystal structure of ethyl 2-methyl-510-dioxo-4-phenyl-510-di­hydro-4H-11-thia-14a-di­aza­benzobfluorene-3-carb­oxy­late

摘要

The title compound, C24H18N2O4S, crystallizes in the ortho­rhom­bic P212121 space group, indicating the existence of only one enanti­omer with an S configuration of the chiral center in the crystal phase. The di­hydro­pyrimidine ring adopts a twist-boat conformation while the quinone ring is slightly non-planar. In the crystal, mol­ecules are linked by weak C—H⋯O and C—H⋯S hydrogen bonds and C—H⋯π inter­actions. In addition, a short inter­molecular S⋯N contact of 3.250 (3) Å indicates an inter­action between the S atom and the π-system of the thia­zole ring.
