A. K. Bauri, S. Foro, H.-J. Lindner and S. K. Nayak

Abstract: 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 -pyran ring adopts a distorted half-chair conformation. An intermolecular C-HO hydrogen bond is observed.
