Bisaxially Coordinated (Tetraphenylporphinato)iron(II) Complexes The coordination behavior of (tetraphenylporphinato)iron(II) (TPPFe) has been studied with the preparation of the monomeric complexes TPPFe(L) 2 with Lpy (pyridine), pyz (pyrazine), 2,6‐dimepyz (2,6‐dimethylpyrazine), bpy (4,4′‐bipyridine), bpyac [1,2‐bis(4‐pyridyl)acetylene], dabco (1,4‐diazabicyclo [2.2.2]octane), and BzINC (benzyl isocyanide). Pure TPPFe has been obtained by thermal decomposition of TPPFe(py) 2 . The monomeric complexes TPPFe(L) 2 with Lpyz, bpy, bpyac, and dabco can be transformed into the bridged systems [TPPFe(L)] n by heating them in toluene or chlorobenzene. The bridged structure of the complexes [TPPFe(L)] n has been confirmed by IR and TG/DTA investigations and especially by Mößbauer spectroscopy. In comparison with the corresponding (phthalocyaninato)iron compounds the bridged TPPFe complexes exhibit lower semi conducting properties even after doping with iodine.
