U. Oetliker et al., LARGE VARIATION OF THE LUMINESCENCE ENERGY FROM RHENIUM(V) COMPLEXES WITH OXO AND NITRIDO LIGANDS, Chemical communications, (6), 1998, pp. 657-658
We observe visible and near-IR luminescence from oxo and nitrido compo
unds of rhenium(v) with chelating ligands combining soft (P) and hard
(O) donors and show that the emitting state energy of the nitrido comp
lexes is higher in energy by a factor of ca, two (8300 cm(-1)) than fo
r the oxo compounds, an unusually large difference.
