Thin-layer chroamtography of pt-metals complexes with ketoanils: Analysis and effect of chelate ring contraction on RF values

Summary Thin-Layer chromatogrtaphy on silica gel was used for the separation of platinum group metal complexes using one-, two-, and three-component solvent systems. In octahedral and square planar, cationic complexes, containing two identical five-membered chelate rings formed by three different ketoanils, a linear dependence on chelate ring contraction (and also metal-ligand bond frequencies and ligand field parameters) of their R_F values has been established in one-component solvent systems.
