Abstract
The structure of the antitumor agent geiparvarin was determined by direct methods from CuKα diffractometer data. The crystals of synthetic geiparvarin have the space groupP21/c witha = 8.305(1),b = 11.077(1),c = 18.287(1) Å, β = 98.79(1) °, andZ = 4. The structure was refined toR = 0.047. The chemically determined structure was confirmed. Bond distances and angles are normal and there are no unusual C-H ⋯ O intermolecular contacts.
