Abstract
The title compound, sodium chromium/aluminium molybdenum/aluminium dodecaoxide, Na0.72Cr0.48Al1.74Mo2.77O12, was prepared by solid-state reaction. Its crystal structure is related to NaSICON-type compounds. The framework is built up fromM1O6(M1 = Cr/Al) octahedra andM2O4(M2 = Mo/Al) tetrahedra interconnected by corners. The three-dimensional framework contains cavities in which sodium cations are located. Two validation models (BVS and CHARDI) were used to confirm the proposed structural model. The mobility of Na+ions in the structure has been investigated by theoretical means.
