Abstract
An alternative method for the synthesis of polycrystalline samples of the phases M(1)Cr(CrO4)(2) (M(1) = Na, K, Rb) is proposed. Crystallogr aphic data of the three isostructural compounds were refined by means of the Rietveld method and their thermal stabilities investigated by T G and DTA methods. The infrared and Raman spectra were interpreted on the basis of a factor group analysis of the internal vibrations of the CrO42- groups.
