Monomeric and Bridged Oligomeric (Tetrasulfophthalocyaninato)iron(II) Complexes with Isocyanides and N‐Donors as Axial Ligands (Tetrasulfophthalocyaninato)iron(II) (TsPcFe) ( 1 ) is treated with the isocyanides tert ‐butyl isocyanide ( t BuNC), 1,4‐diisocyanobenzene (dib), 2,3,5,6‐tetramethyl‐1,4‐diisocyanobenzene (me 4 dib), and 4‐isocyano‐3,5‐dimethylpyridine (me 2 pyNC), and also with pyrazine (pyz) leading to bisaxially coordinated monomers TsPcFe(L) 2 (L= t BuNC, dib, me 4 dib) and the bridged oligomers [TsPcFe(L)] n (Ldib, me 4 dib, me 2 pyNC, and pyz). All these complexes are soluble in methanol or water. The spectroscopic properties of the complexes are described, and the average chain lengths of the bridged oligomers are determined by 1 H‐NMR spectroscopy. The bridged stacked systems exhibit semiconducting properties with and without iodine doping.
