摘要：

A series of chloridoruthenium(II) complexes bearing the tripodal ligand tris(pyrazolyl)borate (Tp), the water-soluble cage phosphane 1,3,5-triaza-7-phosphaadamantane (PTA) and its N-boranyl adduct PTA(BH3), together with PPh3, have been synthesised. The corresponding monohydrido complexes have also been obtained by treating the chlorides with NaOMe. The X-ray crystal structures of [TpRuCl(PTA) (PPh3)] (2) and [TpRuCI(PTA)(2)] (3) are also described. Cyclic voltammetry (CV) studies in MeCN and dmso generally show reversible Ru-II/III oxidation waves and the values of E-1/2(OX) reflect the electron-donating character of the ligands [Tp (each arm) > PTA > PTA(BH3)], whose Lever electrochemical parameter (E-L) has been estimated for the first time.
