Abstract

The versatile NO₂ ^- ligand is a chelating, bidentate ligand in the high symmetry M₂M′Eu(NO₂)₆ (M = Cs, Rb; M′ = Na, Li) systems. The investigation of the vibronic structure and energy levels of these systems is of interest for comparison with the abundant data from Cs₂NaEuX₆ (X = F, Cl) crystals. The vibrational structure in the electronic emission spectra of the hexanitritolanthanates has been investigated from the analysis of the 10 K and 100 K spectra. Most of the vibronic intensity of the ⁵D₀ → ⁷F₀, ⁷F₂ transitions is due to low energy skeletal modes which correlate with τ_u (T _h) infrared vibrations. The energy levels derived from the vibronic analysis indicate a weak crystal field in these systems. © 2010 Elsevier B.V. All rights reserved.
