1,1'-Bis(ferrocenylphenylphosphino)-ferrocene

Abstract

In the title compound, [Fe3(C5H5)2(C16H13P)2], two (C6H5)P-[(C5H4)Fe(C5H5)](C5H4) units are bridged by an Fe atom, located on an inversion center, giving a central third ferrocene unit. Each Fe atom is coordinated by two cyclopentadienyl rings in a parallel sandwich fashion, with twisted conformations. The geometry of the phosphine P atom is pseudotetrahedral, defined by a phenyl ring, two cyclopentadienyl rings and an electron pair.
