Bisaxially Coordinated (Tetraphenylporphinato)iron(II) ComplexesThe coordination behavior of (tetraphenylporphinato)iron(II) (TPPFe) has been studied with the preparation of the monomeric complexes TPPFe(L)2 with L=py (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 L=pyz, 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.
