1,10-Bis[bis(4-methoxyphenyl)phosphan- yl]ferrocene

R factor = 0.026; wR factor = 0.070; data-to-parameter ratio = 14.1. 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 cyclopentadienyl conforma-tion with a ring centroid separation of 3.292 (7) A ̊ 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).
