High-valent iron phthalocyanine five- and six-coordinated ?-carbido dimers

The ?-carbido dimer [(PcFe)2C] and its derivatives of formula [{(L)PcFe}2C] (L = acetone, pyridine, 4-methylpyridine, 1-methylimidazole, piperidine) have been prepared and studied by IR, Mössbauer, EPR, and NMR spectroscopy and magnetic susceptibility determinations. All of the complexes appear to contain Fe(IV).
