The effect of the electronegativity of donor atoms on
R F values obtained by TLC on silica gel was investigated
with two series of complexes of the type [M(acac)3_ n
!phacphac)n ] and [M(acac)3_n(phacphSac)n], where M
Is Co(III), Cr(III) or Ru(III), acac = 2,4-pentandionato
ion, phacphac = 1,3-diphenyl-l,3-propanedionato ion
and phacphSac = 3-mercapto-l,3-diphenyl-prop-2-en-
1-on ion (n = 0-3). Development was with nine single
and six two-component solvent systems. The RF values
of the complexes increase by replacing one oxygen
atom of a beta-diketonato ligand with a less electronegative
sulphur atom. A positive linear dependence between
the R M values of the complexes and the numbers of
acac substituted by phacphSac ligands was established.
The separation mechanisms and separation factors are
discussed.
