| Abstract: | Synthesis and characterization of the polyoxometallate (NH4)42Mo72VIMo60VO372(H3CCOO)30(H2O)72]30H3CCOONH4 · 250H2O (Mo132) with the buckyball structure were carried out. New crystallographic data were obtained. Stability of Mo132 was studied
as a function of external factors, acidity, concentration of the solution, and the presence of a polymeric component. The
composition of the most stable complexes of buckyballs with polymers was confirmed. The aggregation of buckyballs in the presence
of polyvinylpyrrolidone were studied. Thermochemical studies of Mo132 interaction with polyvinyl alcohol in films were carried
out. Electromigration of polymer-salt complexes in solutions was established, the possibility of change of the sign of associates
upon interaction of Mo132 anions with lanthanum cations was confirmed. |
