Abstract:
The results of X-ray structural, IR and Raman spectroscopic, and thermodynamic studies of alkali metal molybdates and tungstates A2MnO3n+1 (A = Li, Na, K, Rb, Cs; M = Mo, W) are reviewed and analysed. The dependence of the vibrational spectra, activation energies, and crystal lattice energies on features of the structures of these compounds is discussed. The bibliography includes 51 references.
