Several attempts to prepare (tBu4Pc)Ru only led to an impure product (tBu4Pc)RuLx.This reacts quantitatively with pyridine to form (tBu4Pc)Ru(py)2, easily purified by chromatography.In addition the preparation of (tBu4Pc)RuL2 with L=pyridine, 2-picoline (2-pic), 3-picoline (3-pic), 4-picoline (4-pic), 2,5-lutidine (2,5-lut), and 2,6-lutidine (2,6-lut), respectively, is described.All complexes are characterized by spectroscopic methods including 1H-NMR spectroscopy.Not even in the cases of (tBu4Pc)RuL2 with L=2-pic and 2,5-lut, a careful removal of the ligands L by thermogravimetric methods (TG/DTA) leads to pure (tBu4Pc)Ru.For comparison, the bisadducts PcRuL2 with L=pyridine, picolines (2-pic, 3-pic, 4-pic), lutidines (2,3-lut, 2,5-lut, 2,6-lut), and chloropyridines (2-Clpy and 3-Clpy), respectively, are prepared by treatment of PcRu with an excess of the ligand.For the first time (phthalocyaninato)iron complexes PcFe(2-pic)2, are prepared and characterized by 57Fe Moessbauer spectroscopy.
