Two new polyphosphazene ligands containing 1,10-phenanthrolin-2-olate (L1) and 2,2-bipyridine-6-olate moieties (L2) with 5,5-di-tert-butylbiphenyl-2,2-bis(olate) co-substituents were synthesised and then reacted with Fe(Pyridine)4(NCS)2. Variable temperature Mössbauer and electronic absorbance spectroscopies were used to establish the physical behaviour of the new iron-polyphosphazenes. By attaching two bidentate ligands to a geminal phosphorus atom a pseudo tetradentate ligand can be formed that prevents cross-linking when iron is coordinated to the polyphosphazene.
