Abstract
3α,7 α, 14 α -Trihydroxypregn-16-en-20-one, C21H3204, Mr = 348.48, orthorhombic, P212121, a = 9.211 (1), b = 13.201 (1), c = 16.031 (1) Å, V = 1949.28 (29) Å3, Z = 4, Dx = 1.187 g cm-3, λ(Cu Kα), = 1.5418 Å, μ = 6.07 cm-1, F(000) = 760, T= 293 K, R = 0.061 for 1337 observations. The A, B and C rings adopt normal chair conformations with the D ring in a 14α-envelope conformation. The molecules are held together by two hydrogen bonds [O(3)…O(20) = 2.879 and O(7)…O(14) = 2.612 Å].
