Nature and Isomorphism of Extra-Framework Components in Cancrinite- and Sodalite-Related Minerals: New Data

New data on the isomorphism of extra-framework components (including chromophores) in two- and multilayer minerals belonging to cancrinite sodalite groups, are obtained using chemical single-crystal X-ray diffraction as well infrared, Raman, ESR, UV–Vis–near IR absorption photoluminescence spectroscopy methods. It is shown that blue color these may be due CO3•? or S3•? radical anions, whereas yellow pink shadings typically presence S2•? anions S4•? S4, respectively. Two kyanoxalite varieties distinguished: (1) with predominantly acid oxalate groups (2) neutral groups. Zundel cation H5O2+ CO2 molecules typical impurities nosean. The also detected 12-layer, cancrinite-related mineral marinellite. Wide isomorphic series involving substitutions SO4? for SO32? CO32?, OH? H2O F?, common eight-layer, cancrinite-group an afghanite-type framework.
