Kravchenko O. Complexation of Pd(II) and Pt(II) with crowns - ethers and thioamide ligands, immobilized on polimer and silica surface.

It is established, that at fastening on a surface of a polymer of crowns-ethers and thioamide ligands their electronic structure changes. It results that the complexes Pd(II) and Pt(II) with such ligands differ on composition, structure and properties from similar complexes in solutions. All researched ligands are capable to form polynuclear complexes with Pd(II). The meanings of constants of linkage Pd(II) and Pt(II) graft on a surface by crowns - ethers and thioamide ligands testify that Pt(II) forms more steadier complexes then Pd(II). The hardness of linkage Pd(II) from solutions of different salts is increased in a line Pd(ClO4)2 > K2PdCl4 > [Pd(NH3)4]Cl2. Thioamide ligands on meanings of constants of linkage Pd(II) and Pt(II) can be arranged in a line [R]-tu < [R]-tsc < [R]-dto.
