| Abstract: | The octahedral cationic CoIII complexes Co(ida)(bigH)2]+, Co(glyO)(bigH)2]2+, Co(α-alanO)(bigH)2]2+, Co(β-alanO)BigH)2]2+ and Co(PhbigH)3]3+, where idaH2=iminodiacetic acid, glyOH=glycine, α-alanOH=α-alanine, β-alanOH=β-alanine and PhbigH=phenylbiguanide, were studied by thin-layer
chromatography on silica gel in solutions of different electrolytes (NaCl, NaBr, NaI, Na2SO4, Na2S2O3, NaNO2 and NaNO3). Among other factors, the movement of the cationic complexes was found to be dependent on the surface tension and equivalent
conductance of the developer electrolyte. |
