Potassium dicyano(2,3-naphthalocyaninato)ferrate(III), K[2,3-NcFe(CN)2] (2), reacts in water with elimination of KCN to form μ-cyano(2,3-naphthalocyaninato)iron(III), [2,3-NcFe(CN)]n (4a). Dichloro(2,3-naphthalocyaninato)iron(III), 2,3-NcFeCl2 (3), reacts with KCN to yield also [2,3-NcFe(CN)]n (4b). Both compounds 4a and 4b show similar IR spectra with a typical blue-shifted CN valence frequency caused by a bridging function of CN-. Compounds 4a and 4b also show almost identical 57Fe-Mössbauer spectra which, however, might be interpreted with a Fe(+II) oxidation state of the iron. The measured magnetic moment of 4 however clearly proves the expected oxidation state +III of the iron in [2,3-NcFe(CN)]n (4). Compounds 4a and 4b both exhibit good semiconducting properties (σRT ∼ 10-3 S/cm) without additional external oxidative doping. The property is quite similar to that of the known μ-cyano(phthalocyaninato)iron [PcFe(CN)]n (σRT ∼ 10-2 S/cm).
