In the title compound, [Fe(C5H5)(C5H6O3P)], the phosphate group is bonded to the ferrocene unit with a P-C bond length of 1.749 (3) Å. In the crystal, six ferrocenylphosphonic acid molecules are connected by 12 strong intermolecular O-HO hydrogen bonds, leading to the formation of a highly distorted octahedral cage. The volume of the octahedral cage is about 270 Å3.
