X-ray powder diffraction data for norethindrone

摘要

Experimental X-ray powder diffraction data, unit-cell parameters, and space group for norethindrone, C_(20)H_(26)O_2, are reported [a = 20.7484(12) A,b= 12.1678(9) A, c = 6.5561(2) A, α = β = γ= 90°, unit-cell volume V= 1655.17(16) A~3, Z=4 and space group P2_12_12_1]. All measured lines were indexed and are consistent with the F2_12_12_1 space group. No detectable impurity was observed.
