Description:
The crystal structure of seselin (2′,2′-dimethyl-3-pyreno[6,5:7,8]coumarin), C14H12O3, a bioactive pyrenocoumarin, has been reinvestigated. The coumarin ring system is nearly planar and the α-pyran ring adopts a distorted half-chair conformation. An intermolecular C—H...O hydrogen bond is observed.
