Crystal structure of flumethasone, C <sub>22</sub> H <sub>28</sub> F <sub>2</sub> O <sub>5</sub>
Abstract The crystal structure of flumethasone has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional theory techniques. Flumethasone crystallizes in space group P2 1 (#4) with a = 6.46741(5), b = 24.91607(20), c = 12.23875(11) Å, β = 90.9512(6)°, V = 1971.91(4) Å 3 , and Z = 4 at 298 K. The crystal structure consists of O–H⋯O hydrogen-bonded double layers of flumethasone molecules parallel to the ac -plane. The powder pattern has been submitted to ICDD for inclusion in the Powder Diffraction File™ (PDF®).
