The effect of the composition of mixed tris-beta-diketonato metal complexes on their hR(F) Values obtained by a thin layer of polyacrylonitrile sorbent was examined 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-pentanedionato ion, phacphac = 1,3-diphenyl-1,3-propanedionato ion and phacphSac = 3-mercapto-1,3-diphenyl-prop-2-en-1-on ion (n = 0-3). Ten mobile phases were used for their chromatographic separation. In all instances hR(F) values of the examined complexes decrease when the oxygen atom in beta-diketonato ligand is substituted by a less electronegative sulphur atom. It has also been established that the substitution of acac ligand results in a hR(F) value decrease. In all the examined cases a linear dependence between the R-M values of the complexes and the number of acac ligands substituted by phacphSac ligands was established. The separation mechanisms and the separatio...n factors are discussed. (C) 1999 Elsevier Science B.V. AU rights reserved.
