采用衍生分析（TG、DTA 和 DTG）结合质谱、FTIR 光谱以及吸水实验研究了 (NH4)(32) [Mo-110(VI) Mo-28(V) O-416 H-6 (H2O)(58) (CH3COO)(6)] 的热性能。约 250 H2O (1) 呈现纳米级“巨轮”阴离子。讨论了样品转变的特定阶段，并将其与已知的单晶 X 射线结构（1）进行了比较。巨型轮式簇在高达 350 摄氏度的温度下大约保持稳定。有趣的是，这个复杂的系统可以被正式地视为嵌入水分子“海洋”中的纳米结构景观。 (C) 2002 Elsevier Science B.V. 保留所有权利。
Derivatographic analysis (TG, DTA and DTG) coupled with mass spectrometry, FTIR spectroscopy as well as water sorption experiments were used to study the thermal properties of (NH4)(32) [Mo-110(VI) Mo-28(V) O-416 H-6 (H2O)(58) (CH3COO)(6)]. approximately 250 H2O (1) exhibiting the nanosized 'giant wheel' anion. The particular stages of sample transformations are discussed and compared with the known single crystal X-ray structure of (1). The giant wheel type clusters appear approximately to be stable up to 350 degreesC. Interestingly, the complex system can be formally considered as a nanostructured landscape embedded in an 'ocean' of water molecules. (C) 2002 Elsevier Science B.V. All rights reserved.
