| Özet |
| Manganese-containing enzymes play an important role in the oxygen metabolism [1], and in particular in photosynthesis [2, 3]. Numerous synthetic high-oxidationstate manganese complexes with Schiff base ligands and their Mn (II) precursors have attracted considerable interest as oxygen-carrier biomimetic models [4-7]. A large series of Mn (II) complex with tetradentate ligands derived from salicylaldehyde and α, ω-diaminoalkanes have been synthesized and have been shown to react with dioxygen forming Mn (III) or Mn (IV) species. The structure of these complexes has been subjected a discussion since they may exit as monomeric, olygomeric or polymeric species, containing tetrahedraly coordinated Mn (II)[4]. The monomeric species should contain a tricyclic chelate system which is expectable to exhibit interesting conformational behaviour, especially when the aliphatic chain between the two donor nitrogen atoms is enough long.The molecular mechanics and semi-empirical methods, being less time consuming as compared to the ab-initio methods are widely used tools of the theoretical conformational analysis and give reliable results when applied to organic molecules [8]. MM and semi-empirical calculations of inorganic and bioinorganic systems have been intensively studied in early stage calculations [7, 9-10]. |
