Triamcinolone acetonide methanol 0.67-solvate at 170 K

I. Jeß and C. Näther

Abstract: In the crystal structure of the title compound (systematic name: 9-fluoro-11,21-dihydroxy-16,17-isopropylidene-dioxypregna-1,4-diene-3,20-dione methanol 0.67-solvate), C₂₄H₃₁FO₆·0.67CH₃OH, the molecules are connected via O-HO hydrogen bonding. In this arrangement, channels are formed which are elongated in the direction of the crystallographic c axis. In these channels, methanol molecules are included with the C atoms located on the threefold axis. Therefore, the O atoms are disordered over three orientations. One of the two crystallographically independent solvent molecules is connected to the triamcinolone acetonide molecules via O-HO hydrogen bonding.
