The reaction of HOC6H4CH2CN, N3P3(O2Cl2H8)(2)(OC6H4CH2CN)(2) and - [{NP(O2C12H8)}(0.8) {NP (OC6H4CH2CN)(2)}(0.18)](n) with Cp*Fe(dppe)I in dichloromethane solution and in the presence of TIPF6 affords the new compounds [Cp*Fe(dppe)NCCH2C6H4OH][PF6] 1 CP*=C-5(CH3)(5) [N3P3(O2Cl2H8)(2)(OC6H4CH2CN.Cp*Fe(dppe))(2)] [PF6](2) 2 and the copolymer [{NP{(O2C12H8)}(0.8) {NP(OC6H4CH2CN.[Cp*Fe(dppe)][PF6])(2)}(0.18)](n) 3 respectively. The a coordination of the Cp*Fe(dppe) fragment toward the nitrile group is indicated by spectroscopic data. The copolymer 3 is soluble in several organic solvents with no significant cross-linking and has a Mw on the order of 1.260.000. Thermal effects of the incorporation of the organometallic fragment to the copolymer were investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
