Abstract A series of bis‐[3]ferrocenophanes of the general type Fe(C 5 H 4 E’) 2 E−E(E'C 5 H 4 ) 2 Fe (E=P, SiH and E’=P t Bu, N neo Pentyl, NSi(CH 3 ) 3 ) with an isolobal molecular framework have been prepared and characterized by heteronuclear NMR spectroscopy and X‐ray crystallography. The thermal dissociation behavior with respect to homolytic fission of the central bond generating phosphorus centered radicals was investigated using EPR spectroscopy and quantum chemical calculations.
