Назив: | Thermal analysis of Fe(III) complexes with salicylaldehyde semi-, thiosemi- and s-methylisothiosemi-carbazones | Аутори: | Petrović A. Petrović D. Leovac V. Budimir M. |
Датум издавања: | 1-дец-1999 | Часопис: | Journal of Thermal Analysis and Calorimetry | Сажетак: | The paper describes the results of differential thermal analysis of the octahedral Fe(III) complexes of the general formula [Fe(HLn)2]Cl and Fe(HL3)L3, as well as of the corresponding ligands H2Ln (H2Ln - tridentate salicylaldehyde semi thiosemi- and S-methylisothiosemi-carabazones with n=1, 2 and 3 respectively). The decomposition of the complexes involving sulphur-containing ligands (H2L2 and H2L3) starts with sulphur elimination. In case of the complexes [Fe(HL2)]Cl and [Fe(HL3)]Cl sulphur evolves independently, whereas with Fe(HL3)L3 it is eliminated within the SCH3 group. In the former case, sulphur elimination takes place at the same temperature for both complexes. The change in the coordination mode, being a consequence of the replacement of O by S, has no essential effect on thermal stability of the coordination polyhedron. The complexes involving ONN coordination, realized with the H2L3 ligand, exhibit a comparatively highest thermal stability of the coordination polyhedron. | URI: | https://open.uns.ac.rs/handle/123456789/13772 | ISSN: | 13886150 |
