| Abstract: | The electronic spectrum of the nitridoosmate(VIII) ion, OsO3N-, has been measured at liquid helium temperatures for thin films of the n-tetrabutyl-ammonium salt and for oriented, doped LiClO4. 3H2O single crystals. Four structured band systems, all individually composed of superimposed A 1 ← A 1 and E←A 1 transitions, are observed at energies comparable to those of the two lowest 1 T 2←1 A 1 transitions of OsO4. Prominent vibronic structure assigned to ν(Os-N) is observed for all of the bands. The bands are assigned to transitions to completely spin-orbit mixed states. The highest filled orbitals of OsO3N- are oxygen-localized and π non-bonding. The nitrido ligand appears to ‘dominate’ the π-bonding in the ion. |
