SYNTHESIS, SPECTROSCOPIC AND ELECTROCHEMICAL STUDY OF CATIONIC CICLOPENTADIENYLIRON(DIPHOSPHINE) COMPLEXES SUPPORTED ON A HIGH MOLECULAR WEIGHT PHOSPHAZENE POLYMER THROUGH NITRILE LIGANDS

The high molecular weight phosphazene random copolymer {[NP(OC6H5)2]0.94 [NP(OC6H5)(OC6H4CNFe(dppe)Cp)]0.06[PF6]0.06}n (1), that carries [Fe(dppe)Cp] cationic fragments coordinated to nitrile side groups, has been synthesized from the copolymer {[NP(OC6H5)2]0.94[NP(OC6H5)(OC6H4CN)]0.06}n and the com...
