“…In the whole temperature range studied, the linewidths are large, much larger than the one found in pure A12C16 (1). In addition, the 27Al NMR signals obtained for the lanthanum system at various temperatures are much broader compared to the corresponding signals of the yttrium system.…”

“…The formation of viscous liquids and glasses in rare earth chloride-aluminum chloride (REC13-A1C13: RE = Y, La, Nd, Gd, Ho) binary systems has recently been es tablished, and vibrational Raman spectroscopy has been used in order to examine the structural properties and de termine the glass forming composition ranges of these systems [1][2][3]. In the proposed structural models the main participating units are 'A1C14' and in part 'A12C17' [1][2][3], which are linked to the RE so as to satisfy its pref erential coordination, being 8 or 9.…”

27 AI NMR spectra of pure crystalline and molten A1C13 and of RECI3-AICI3 (RE = Y, La) glass form ing binary mixtures have been obtained. Compositions corresponding mainly to YC13/A1C13 = 1/3 and LaCiyAlC^ = 1/3.7 have been studied from the glassy and crystalline state up to the melt. The 27A1 spectra can be unambiguously assigned to four-coordinated Al-species, such as A12C16, 'A1C14', and 'A12C17\ The chemical shifts lie between 95 and 110 ppm, very well separated with the -1.6 ppm giv en by the 'A1C16' coordination in solid A1C13. From the temperature evolution of the 27Al NMR spec tra, a description for the dynamic behaviour of these systems is proposed.
