Abstract
In the title compound C27H19ClO6, the coumarin ring system is not exactly planar, with a dihedral angle of 4.12 (7)° between its benzene and lactone rings. The cis-fused pyran rings adopt half-chair conformations. The carbomethoxy and chlorophenyl groups are in a trans configuration. The crystal packing is stabilized by intermolecular C—H⋯O interactions, which produce a centrosymmetric R 2 2(14) dimer and two centrosymmetric R 2 2(18) dimers connecting the molecules in a two-dimensional fashion.
