本文报道了Na包封的Preyssler型磷钨酸盐K盐K14[P5 W30 O 110 Na（side）（H2O）]和K14[P5 W30 O 110 Na（center）]的热驱动固态转变。K14[P5 W30 O 110 Na（side）（H2O）]在其中一个侧腔中含有一个Na+和一个配位H2O分子，而K14[P5 W30 O 110 Na（center）]在中心腔中含有一个Na+。K14[P5 W30 O 110 Na（side）（H2O）]的加热产生[P5 W30 O 110 Na（center）]14-、[P5 W30 O 110 K（center）]14-和[P5 W30 O 110 K（side）2]13-。[P5 W30 O 110 K（中心）]14-和[P5 W30 O 110 K（侧）2]13-分别在中心腔中含有单K+和在两个侧腔中含有双K+。[P5 W30 O 110 Na（中心）]14-的钾盐加热产生[P5 W30 O 110 K（中心）]14-和[P5 W30 O 110 K（侧）2]13-。这些结果表明，在200-500 °C下加热导致Na+和K+的迁移，而没有分子的崩溃。K14[P5 W30 O 110 Na（side）（H2O）]通过反复固态加热成功转化为K12 Na [P5 W30 O 110 K（side）2]，该固态加热通过在H2O中溶解和干燥而定期中断。
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.
