Abstract: The title anion radical chelates are of type [RuII (L•̶)(Cl)(CO)(PPh3)2] where L is azo-2,2'-bipyridine (abp), 2-(p-chlorophenylazo)pyridine (Clpap) or 2-(phenylazo)pyridine (pap) and L•̶  is the corresponding azo anion radical. These spontaneously reduce protons in solution and secondary reactions may then follow. In this manner (the acids being HPF6, HCl and HC=CPh), the following species have been isolated and structurally characterized [Ru(abp )(Cl)(CO)-(PPh3)2]PF6 , [Ru(Clpap)(Cl)2 [(CO)(PPh3)].CH2Cl2 and [Ru(pap) (Cl)1.5 (C2Ph)0.5 (CO)-(PPh3)]·CH2Cl2.
