摘要：

The stability of the ammonium phospho-molybdic Dawson-type salt (NH4)(6)P2Mo18O62.12H(2)O in aqueous solution has been studied. The polyanion P2Mo18O626- decomposes into the lacunar Keggin-type anion HxPMo(11)O(39)((7-x)-), HxMo5P2O23(6-x)-, phosphate and oxomolybdate species, regardless of the concentration and acid-base conditions.
