Abstract

Synthetic sodalite structures containing silver, cadmium and lead cations have been obtained and structurally identified. In order to examine the changes in sodalite spectra envelope resulting from the substitution of initial sodium cations by Ag+, Cd2+ and Pb2+, a series of theoretical sodalite model structures with various Me/Na ratio and different anions have been prepared. Based on ab initio calculations and experimental results, it has been determined how the type and amount of both extra framework cations and anions affect the vibrational spectra and structural properties of sodalite. Additionally, an attempt to identified of bands associated with the individual cations and anions vibration has been undertaken.
