چکیده
In the crystal structure of the title substituted ferrocene complex, [Fe(C₁₉H₁₈O₂P)₂], the Fe(II) atom lies on a twofold rotation axis, giving an eclipsed cyclo-penta-dienyl conformation with a ring centroid separation of 3.292 (7) Å and an Fe-C bond-length range of 2.0239 (15)-2.0521 (15) Å. In the ligand, the cyclo-penta-dienyl ring forms dihedral angles of 60.36 (6) and 82.93 (6)° with the two benzene rings of the diphenyl-phosphine group, while the dihedral angle between the benzene rings is 67.4 (5)°.
