Concerning the electronic structure of the ions M(bpy)/sub 3//sup 3 +/ (M = Fe, Ru, Os; bpy = 2,2'-bipyridine)
In the complexes M(bpy)/sub 3//sup 3 +/ (M = iron (Fe), ruthenium (Ru), osmium (Os); bpy = 2,2'-bipyridine), the metal d..pi..(t/sub 2g/) orbitals are resolved into A/sub 1/ and E components. Analyses of the electronic absorption and EPR spectra show that the A/sub 1/ orbital lies higher in energy than the E orbitals, so that the complexes have an /sup 2/A/sub 1/ ground state. An /sup 2/A/sub 1/ ground state is consistent with theoretical expectations. Further, the orbital splitting in the d..pi.. levels is argued to increase in the order Fe < Ru < Os. The information obtained in the analysis should prove useful in analyzing the metal to ligand charge-transfer (MLCT) absorption spectra of the analogous species M(bpy)/sub 3//sup 2 +/. 2 figures, 1 table.
