The heat‐driven solid‐state transformations of K salts of the Na‐encapsulated Preyssler‐type phosphotungstates, K₁₄[P₅W₃₀O₁₁₀Na(side)(H₂O)] and K₁₄[P₅W₃₀O₁₁₀Na(center)], are reported herein. K₁₄[P₅W₃₀O₁₁₀Na(side)(H₂O)] contains one Na⁺ in one of the side cavities and a coordinating H₂O molecule while K₁₄[P₅W₃₀O₁₁₀Na(center)] contains one Na⁺ in the central cavity. The heating of K₁₄[P₅W₃₀O₁₁₀Na(side)(H₂O)] produces [P₅W₃₀O₁₁₀Na(center)]^14–, [P₅W₃₀O₁₁₀K(center)]^14–, and [P₅W₃₀O₁₁₀K(side)₂]^13–. [P₅W₃₀O₁₁₀K(center)]^14– and [P₅W₃₀O₁₁₀K(side)₂]^13– contain mono‐K⁺ in the central cavity and di‐K⁺ in both side cavities, respectively. The heating of potassium salt of [P₅W₃₀O₁₁₀Na(center)]^14– produces [P₅W₃₀O₁₁₀K(center)]^14– and [P₅W₃₀O₁₁₀K(side)₂]^13–. These results indicate that heating, at 200–500 °C, causes the migrations of Na⁺ and K⁺, without the collapse of the molecule. K₁₄[P₅W₃₀O₁₁₀Na(side)(H₂O)] was successfully converted to K₁₂Na[P₅W₃₀O₁₁₀K(side)₂] by repeated solid‐state heating, which was periodically interrupted by dissolution, in H₂O, and drying.

在Presssler型磷钨酸盐中进行固态离子迁移以制备双钾阳离子包封的衍生物

Na包裹的Preyssler型磷钨酸盐的K盐，K ₁₄ [P ₅ W ₃₀ O ₁₁₀ Na（side）（H ₂ O）]和K ₁₄ [P ₅ W ₃₀ O ₁₁₀ ]的K盐的热驱动固态转变Na（中心）]，在本文报道。K ₁₄ [P ₅ W ₃₀ O ₁₁₀ Na（侧）（H ₂ O）]在一个侧腔中包含一个Na ⁺和一个配位的H ₂ O分子，而K ₁₄ [P ₅ W ₃₀ O ₁₁₀Na（中心）]在中心腔中包含一个Na ⁺。K ₁₄ [P ₅ W ₃₀ O ₁₁₀ Na（侧面）（H ₂ O）]的加热产生[P ₅ W ₃₀ O ₁₁₀ Na（中央）] ^14–，[P ₅ W ₃₀ O ₁₁₀ K（中央）] ^14–和[P ₅ W ₃₀ O ₁₁₀ K（side）₂ ] ^13–。[P ₅ W ₃₀ O ₁₁₀ K（中心）] ^14–和[P ₅ W₃₀ O ₁₁₀ K（side）₂ ] ^13–分别在中心腔中包含mono- K ⁺，在两个侧腔中包含di-K ⁺。加热[P ₅ W ₃₀ O ₁₁₀ Na（中心）] ^14–的钾盐会产生[P ₅ W ₃₀ O ₁₁₀ K（中心）] ^14–和[P ₅ W ₃₀ O ₁₁₀ K（侧面）₂ ] ^{13 –}。这些结果表明，在200–500°C的温度下加热会导致Na ⁺和K ⁺迁移，而分子不会崩溃。通过反复进行固态加热，将K ₁₄ [P ₅ W ₃₀ O ₁₁₀ Na（侧）（H ₂ O）]成功转化为K ₁₂ Na [P ₅ W ₃₀ O ₁₁₀ K（侧）₂ ]，该过程定期中断通过溶解在H ₂ O中并干燥。
