Abstract

The reactions of 1-methyl-2-(p-chlorophenylazo)imidazole (L1) and 2-(phenylazo)pyridine (L2) with [Ru(H)(X)- (CO)(PPh3)3] (X = Cl, Br) have afforded the green paramagnetic (S = ½) and EPR-active (g ≈ 2.00) title anion radical complexes [Ru(L1·–)(Cl)(CO)(PPh3)2] 1 and [Ru(L2·–)(Br)(CO)(PPh3)2] 2 in which the N–N bond lengths lie near 1.35 Å.
