Synthesis and Characterization of a New Family of Thermally Stable Open-Framework Zincophosphate/Arsenate Phases: M<sub>3</sub>Zn<sub>4</sub>O(XO<sub>4</sub>)<sub>3</sub>·<i>n</i>H<sub>2</sub>O (M = Na, K, Rb, Li, ...; X = P, As; <i>n</i> = ∼3.5−6). Crystal Structures of Rb<sub>3</sub>Zn<sub>4</sub>O(PO<sub>4</sub>)<sub>3</sub>·3.5H<sub>2</sub>O, K<sub>3</sub>Zn<sub>4</sub>O(AsO<sub>4</sub>)<sub>3</sub>·4H<sub>2</sub>O, and Na<sub>3</sub>Zn<sub>4</sub>O(PO<sub>4</sub>)<sub>3</sub>·6H<sub>2</sub>O
The syntheses, representative crystal structures, and some properties of a new family of microporous zincophosphate/arsenate materials, denoted M3Zn4O(XO4)3·nH2O (M = Li, Na, K,...
