Анотація

The presence of hypochromic shift in the heteropoly salt solution was established that is caused by the change in coordination polyhedron of Eu(III) ion during transition from aqua complex to Peacock-Weakley heteropolyanion with coordination towards the heteroatom of lacunar pentatungstate anions.
