9-(2-Chloro­phen­yl)-4a-hy­droxy-3,4,4a,5,6,7,9,9a-octa­hydro-2H-xanthene-1,8-dione

In the title compound, C(19)H(19)ClO(4), the di­hydro­pyran ring and the cyclo­hexane ring adopt a half-chair conformation and a chair conformation, respectively. The cyclo­hexene ring has an envelope conformation with the central CH(2) C atom as the flap. This atom is disordered over two positions...

description In the title compound, C(19)H(19)ClO(4), the di­hydro­pyran ring and the cyclo­hexane ring adopt a half-chair conformation and a chair conformation, respectively. The cyclo­hexene ring has an envelope conformation with the central CH(2) C atom as the flap. This atom is disordered over two positions [site-occupancy ratio = 0.744 (12):0.256 (12)] above and below the mean plane formed by the other five atoms. In the crystal, O—H⋯O hydrogen bonds between hy­droxy and carbonyl groups link mol­ecules into chains propagating along [001].
