Rubidium gadolinium bis(tungstate).

Focuses on the study conducted by Chinese scientists on determining the structure of rubidium gadolinium bis(tungstate). Composition of the crystal with corner- and edge-sharing WO₆ octahedral and GdO₈ polyhedral groups; Significance of the WO₆ octahedral and GdO₈ polyhedral groups in giving rise to a Gd-WO₄ polyhedral backbone surrounding structural cavities filled with rubidium cations; Significance of the structure of the Gd and Rb atoms in the twofold axes.
