Abstract
Results of spectroscopic investigations related to complex compositions of 3-substituted derivatives of pentane-2,4-dione (β-diketonate) complexes with chosen d- and f-metal ions are presented. Ligands 3-allylacetylacetone (3all-acac) and 3-benzylacetylacetone (3ben-acac) were prepared and used for the complexation study with Cu(II), Co(II), Nd(III), and Ho(III) metal ions. Based on the absorption spectra of lanthanide ions in their hypersensitive transitions, with the use of computer assisted target factor analysis (CAT) and absorption spectra of the ligands with Cu(II) and Co(II), the verification of complex compositions and the determination of their stability constants were achieved. In case of Nd(III) and Ho(III) complexes with β-diketone ligands, absorption of their maxima were studied in the range of hypersensitive transitions 4 I 9/2 → 4 F 7/2 + 4 S 3/2 (λ max ∼ 734 nm and 748 nm) for Nd(III) and in the range of 435–465 nm, corresponding to the hypersensitive transition 5 G 6 → 5 I 8 (λ max ∼ 450 nm), for Ho(III).
