Excited state properties of silver(I) nitrite complexes: Nitrogen conproportionation in Ag(NH3)NO2 induced by LLCT excitation

The complex Ag(NH3)NO2, which can be viewed as a ligand-based mixed-valence compound, undergoes a photoconproportionation of nitrogen from −III and +III to 0. It is suggested that this photolysis originates from a NH3 to image LLCT state which is populated from a image IL state. In this context, the excited state properties of AgNO2 and Ag(H2O)NO2 are also discussed.
