摘要: Abstract A new and convenient route for preparation of [Ru(trpy)(H2O)3]2+ involving reductive cleavage the corresponding oxo dimers has been established. Furthermore, complexes bearing tridentate facial ligand tpm (tris(1-pyrazolyl)methane) meridional trpy (2,2′:6′,2″-terpyridine) have prepared from [RuIIL(H2O)3]2+ (L=tpm, trpy) precursors. The obtained with general formula [RuIILL′]2+ L′=py3, py2H2O; L=trpy, L′=trpy, py3, Cl3) spectroscopically electrochemically characterised structure [Ru(tpm)(py)3](PF6)2 [RuCl3(trpy)] determined by means X-ray crystallography.
