A new ferrocene complex, 16-ferrocenylmethyl-3β-hy­droxy­estra-1,3,5(10)-trien-17-one, has been synthesized and structurally characterized by single-crystal X-ray diffraction techniques. The ferrocenylmethyl group is positioned at the β face of the estrone moiety; as a result, a new stereogenic center is formed leading to an R stereochemical configuration. No head-to-tail hydrogen bonding is observed in the crystal packing, as is the case in estrone and other derivatives.
