Abstract

Abstract : X-ray powder diffraction data, unit-cell parameters, and space group for 17- hydroxy-16-methyl-9, 11-epoxypregna-1, 4, 6-triene-3, 20-dione, C22 H26 O4, are reported [ a = 18.435(1) Å, b = 12.269(3) Å, c = 8.251(5) Å, α = 90°, β = 90°, γ = 90°, unit-cell volume V = 1866.43 Å 3, Z = 4, ρ cal = 1.261 g cm −3 and space group P 21 21 21 ]. All measured lines were indexed and are consistent with the P 21 21 21 space group. No detectable impurities were observed.
