摘　　要：对首次合成的钼钒磷杂多酸：Ｈ７［Ｐ２Ｍｏ１７ＶＯ６２］·３９Ｈ２Ｏ、Ｈ８［Ｐ２Ｍｏ１６Ｖ２Ｏ６２］·４１Ｈ２Ｏ、Ｈ９［Ｐ２Ｍｏ１５Ｖ３Ｏ６２］·５１Ｈ２Ｏ、Ｈ９［Ｐ２Ｍｏ１４Ｖ４Ｏ６２Ｈ２］·４５Ｈ２Ｏ和Ｈ９［Ｐ２Ｍｏ１３Ｖ５Ｏ６２Ｈ２］·４１Ｈ２Ｏ、；Ｌａ２Ｈ２［Ｐ２Ｍｏ１６Ｖ２Ｏ６２］·ｘＨ２Ｏ、Ｌａ２Ｈ３［Ｐ２Ｍｏ１５Ｖ３Ｏ６２］·ｘＨ２Ｏ、Ｌａ２Ｈ２［Ｐ２Ｍｏ１４Ｖ４Ｏ６２］·ｘＨ２Ｏ及通式为Ｌｎ２［Ｐ２Ｍｏ１８Ｏ６２］·ｘＨ２Ｏ（Ｌｎ＝Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ、Ｓｍ、Ｇｄ、Ｔｂ、Ｄｙ）的稀土杂多配合物，进行了热重、差热分析，并配合溶解度实验、红外光谱及Ｘ－射线粉末衍谢实验。讨论了这些杂多配合物的热稳定性及杂多酸（盐）热稳定性的判据。We have synthesized the molybdovanado phosphoric acid H7[P2Mo17VO62]·39H2O, H8[P2Mo16V2O62]·41H2O, H9[P2Mo15V3O62]·51H2O, H9[P2Mo14V4O62H2]·45H2O. H9[P2Mo13V5O62H2]·41H2O, La2H2[P2Mo16V2O62]·xH2O, La2H3[P2Mo15V3O62]·xH2O, La2H2[P2Mo14V4O62]·xH2O and the rare-earth heteropoly compounds: Ln2 [P2Mo18O62]·xH2O (Ln=La、Ce、Pr、Nd、Sm、Gd、Tb、Dy). The thermal stability of these compounds was discussed by TG-DTA, solubility test , IR , X-ray powder diffraction. Conditions for determining the thermal stability of these compounds were also studied in this paper.
