Abstract
Reaction of α-amino acids (HL) with [Ru(PPh3)3Cl2] in the presence of a base afforded a family of complexes of type [Ru(PPh3)2(L)2]. These complexes are diamagnetic (low-spin d6, S=0) and show ligand-field transitions in the visible region. 1H and 31P NMR spectra of the complexes indicate the presence of C2 symmetry. Cyclic voltammetry on the [Ru(PPh3)2(L)2] complexes show a reversible ruthenium(II)-ruthenium(III) oxidation in the range 0.30-0.42 V vs. SCE. An irreversible ruthenium(III)-ruthenium(IV) oxidation is also displayed by two complexes near 1.5 V vs. SCE.
