The title compound 17a-acetoxy-21-hydroxy-l,4-pregnadiene-3,2O-dione crystallizes in the orthorhombic space group P 2 2,2! with four molecules in the unit cell and the lattice parameters a = 10.950, b = 11.857, c = 15.634 A. The crystal structure was determined by direct methods and refined by full matrix least squares calculations up to the discrepancy factor R = 0.050.Die Titelverbindung 17a-Acetoxy-21-hydroxy-1,4-pregnadien-3,20-dion kristallisiert in der orthorhombischen Raumgruppe P 2,2,2, mit vier Molekiilen in der Elementarzelle und den Gitterkonstanten a = 10,950, b = 11,857, c = 15,634 A. Die Kristallstruktur wurde mit direkten Methoden bestimmt und mit der Methode der kleinsten Quadrate bis zu einem R-Wert von 0,050 verfeinert.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
