1,1′-Bis[bis(4-methoxyphenyl)phosphanyl]ferrocene

Abstract

In the crystal structure of the title substituted ferrocene complex, [Fe(C19H18O2P)2], the FeII atom lies on a twofold rotation axis, giving an eclipsed cyclopentadienyl 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 cyclopentadienyl ring forms dihedral angles of 60.36 (6) and 82.93 (6)° with the two benzene rings of the diphenylphosphine group, while the dihedral angle between the benzene rings is 67.4 (5)°.
