Abstract:
In acidified aqueous Na2MoO4—Na2WO4 solutions in the pH range corresponding to the existence of the paramolybdate Mo7O6-(24) and the paratungstates W7O6-(24) and H2W12O10-(42) , the mixed heptametallates Mo7-xWxO6-(24) (x= I -6) are formed, detected from the 17O NMR spectrum characteristic of the hepta-forms, with lines from O atoms in a mixed environment. Thus with change in the ratio Mo/W in the solution from 9: I to I :9, five lines are observed from four-coordinated O atoms in the environments OMo4, OMo3W, OMo2W2, OMoW3, and OW4 at 122, 105, 91, 80, and 68 (+-2) p.p.m. respectively. The formation of mixed complexes based on H2W12O10-(42)-is not observed.
