The title compound, [Fe(C5H5)(C8H9P)(C20H20P2)]PF6, was obtained by spontaneous resolution of the racemate from acetone/diethyl ether solution. The cationic piano-stool iron(II) complex exhibits pseudooctahedral coordination geometry, with Fe-P distances of 2.189 (3) and 2.178 (4) Å for the bidentate ligand, and 2.170 (3) Å for the phosphirane ligand. The bond parameters for the phosphirane ligand are in good agreement with those found for related complexes.
