Paper Abstract

Normally, metal oxides dissolve only slightly in chloroaluminate melts, and the oxochloroaluminate species are mostly formulated as Al0Cl2- or Al0+, depending on the acidity of the melt (1,2). In this work a metastable melt with composition NaAl20C15 has been prepared (At ca. 200°C the melt decomposes to NaAlCl4 (I) and AlOCl (s)). By comparing the IR-spectra of the melt and MNDO-generated spectra we have found strong evidences for the existence of complex ions in the melt.
