The redox behavior of representative (por)Ru(NO)Cl complexes (por = OEP, T(p-OMe)PP, T(p-CF 3)PP) have been obtained. The compounds possess linear RuNO moieties as exemplified by the X-ray crystal structure of (T(p-OMe)PP)Ru(NO)Cl (Ru-N-O = 174(2)°, Ru-N(O) = 1.790(17) Å, Ru-Cl = 2.220(6) Å). The first electrooxidations of the (por)Ru(NO)Cl compounds in CH 2Cl 2 occur in the order OEP (+0.51 V) < T(p-OMe)PP (+0.57 V) < T(p-CF 3)PP (+0.84 V) (versus Fc/Fc +). We have utilized infrared reflectance spectroelectrochemistry to determine that the first oxidations are porphyrin centered. In addition, the reductions are largely RuNO centered.
