Solid azides of the types Cs 3La(N 3) 6, Cs 2Nd(N 3) 5, and Cs 4Nd(N 3) 7 can be prepared by metathetical reactions under special precautions. Electronic spectra in diffuse reflectance, infrared and Raman spectra, and magnetic susceptibilities versus temperature and field strength were measured on microcrystalline samples. The data of these new compounds are primarily discussed in view of vibrational properties of the azide ion N 3 −, as ligand and in relation to first insights into the nature of the metal-nitrogen bonds within the coordination polyhedra of La(III) and Nd(III).
