 Title    Über Isopolymolybdatfeststoffe und deren Beziehung zu Isopolymolybdationen in wäßriger Lösung* Concerning Solid Isopolym olybdates an d th e ir R elation to Isopolym olybdate Ions in Aqueous Solution  
 Abstract    After a brief discussion on the output capacity of the methods used for the study of the isopolymetalates, a classification and characterization of the solid isopolymolybdates obtainable from aqueous solution is given, and the relation of the solid isopolymolybdates to the isopolymolybdate ions in solution is studied. A correlation between the occurrence or non-occurrence of a species in a solid and in its solution detectable by Raman spectro­ scopy, the solubility of the solid, and the time necessary for the formation of the solid was found. This gives important informations on the mechanisms of formation of the iso-polym etalate ions. The m ost remarkable result of this investigation is that contrary to the view of the majority of the papers on this subject the octamolybdate ion Mo80 264_ having the structure found by L i n d q v i s t does not occur in important quantities in solution at room temperature. For setting up a reaction scheme on the isopolymolybdates only very few of the confusing multiplicity of the papers give evidentiary informations. Most of the papers are overinterpreted.
