Abstract

The processes of formation of oligomeric systems containing clusters of vanadium, iron, and copper are studied. The conditions for their preparation have been optimized. It is shown that the physicochemical nature of the anion in the composition of metal salts determines the equilibrium position between ions and clusters in the composition of the synthesized oligomers, and anion decrease in the polarizability of the anion by 11.3 times leads to an increase of 2.3–3.2 times in the metal particles located in the oligomer in the form of a cluster.
