摘要：

X-ray powder diffraction data for estra-4,9-diene-3,17-dione, C18H22O2, are reported [a = 9.236(7) angstrom, = 10.294(4) angstrom, c = 15.471(1) angstrom, unit cell volume V= 1471.11 angstrom(3) , Z = 4, and space group P2(1)2(1)2(1)]. All measured lines were indexed and are consistent with the P2(1)2(1)2(1) space group. No detectable impurities were observed. The single-crystallographic data of the compound are also reported [a = 9.2392(7) angstrom, b = 10.2793(5) angstrom, c = 15.4822(7) angstrom, unit cell volume V= 1470.37(15) angstrom(3) , Z = 4, and space group P2(1)2(1)2(1)]. Both single-crystal and powder diffraction methods can get the similar structure data. (C) 2020 International Centre for Diffraction Data.
