The synthesis of novel bis-axially coordinated ruthenium(II) complexes with tetra-15-crown-5-phthalocyanine and N-donor ligands ( R 4 Pc ) Ru ( L 2) ( R 4Pc2- = 4,5,4',5',4'',5'', 4''',5'''- tetrakis(1,4,7,10,13-pentaoxotridecamethylene)phthalocyaninate-ion, L = pyridine (py), isoquino-line (iqnl), triethylamine ( Et 3 N )) is reported. The preparation technique involves the interaction of ( R 4 Pc ) Ru ( CO )( CH 3 OH ) with trimethylamine oxide in an N-donor solvent. The advantage of this method consists in selective carbonyl ejection from ( R 4 Pc ) Ru ( CO ) X with simultaneous substi-tution by N-donor ligands. The application of this procedure allowed us to decrease essentially the reaction time, as compared with photochemical methods, as well as to increase substantially the yield of reaction products. UV-visible, 1 H NMR, FT-IR and mass-spectrometry were used for characterization of the obtained compounds.
