Iron azaphthalocyanines with axial ligands

Abstract

The syntheses of the iron azaphthalocyanines Tetra(2,3-pyrido)porphyrazinato-iron, T(2,3-Py)PFe (1), Tetra(3,4-pyrido)porphyrazinato-iron, T(3,4-Py)PFe (2), Tetrapyrazoporphyrazinato-iron, TPzPFe (3), Tetratertbutyltetrapyrazoporphyrazinato-iron tbu[Formula: see text]TPzPFe (4) is reported. They react with the monodentate pyridine, substituted pyridines, piperidine (pip) and various isontriles to form the corresponding bis-axially substituted porphyrazinato-iron compounds McFeL[Formula: see text]. Bidentate ligands. [Formula: see text] pyrazine (pyz) or diisocyanobenzene (dib), form the polymeric adducts, [Formula: see text] [T(2,3-Py)pyz][Formula: see text] or [T(2,3 Py)PFedib][Formula: see text]. The spectroscopic data ([Formula: see text]H-NMR, IR, UV-vis, Mössbauer) are reported and compared with the analogous phthalocyaninato-iron compounds.
