(Phthalocyaninato)iron(II) and -ruthenium(II) (PcM, M = Fe, Ru) react with aliphatic and aromatic monodentate isocyanides RNC (R = t-Bu, c-HX, Bzl, Ph, Me2ph) with formation of the corresponding bisaxial substituted (phthalocyaninato)metal(II) compounds PcM(RNC)2 (M = Fe, Ru) 1-5.The structures of these soluble compounds were determined by 1H and 13C NMR spectroscopy.The influence of the central metal atom M and of the organic group on the ?-donor-?-acceptor properties of the metal-ligand bonds is investigated by IR spectroscopy.UV/VIS spectroscopy , TG/DTG/DTA measurements and FD mass spectroscopy additionally demonstrate the large differences when changing iron against ruthenium in 1-5.The thermal and mass spectroscopic differences point to the existence of pentacoordinated PcRu(II) compounds.
