Abstract

U okviru ovog diplomskog rada priređeni su momonuklearni oktaedarski kompleksi molibdena(VI) opće formule [MoO2L(D)] (D = MeOH, py, 3-Mepy i 4-Mepy); (1-8) diknuklearni kompleksi molibdena (VI) opće formule [MoO2L]2(4,4-bipy); (9-10) i polinuklearni kompleksi molibdena(VI) opće formule [MoO2L]n; (11-12). Svi priređeni spojevi sadrže cis-MoO22+ jezgru na koju je kao tridentatni O,N,O donorski ligand vezana jedna nesimetrična Schiffova baza, L = 3-((2-hidroksi-4-metilfenil)amino)-1-fenilbut-2-en-1-on ili 3-((2-hidroksi-5-metilfenil)amino)-1-fenilbut-2-en-1-on. Na 6. koordinacijsko mjesto tj. u trans položaju u odnosu na terminalni kisikov atom je vezana kao N ili O donor neutralna molekula Lewisove baze. Na priređenim mononuklearnim kompleksima ispitivane su reakcije izmjene liganada vezanih na šesto koordinacijsko mjesto. Reakcije su provedene u otopini i u čvrstom stanju. Svi novopriređeni spojevi su okarakterizirani na temelju podataka dobivenih iz infracrvenih spekta

Abstract (english)

In this thesis novel mononuclear octahedral complexes of molybdenum(VI) [MoO2L(D)] (D = MeOH, py, 3-Mepy and 4-Mepy); (1-8), dinuclear complexes of molybdenum(VI) [MoO2L]2(4,4-bipy); (9-10) and polynuclear complexes of molybdenum(VI) [MoO2L]n; (11-12) were prepared. All prepared complexes contain cis-MoO22+ moiety on which asymmetric Schiff base, L= 3-((2-hydroxy-4-methylphenyl)amino)-1-phenylbuth-2-ene-1-one or 3-((2-hydroxy-5-methylphenyl)amino)-1-phenylbuth-2-ene-1-one, is coordinated as a tridentate O,N,O donor ligand. The 6th coordination place in trans position with respect to the terminal oxygen atom is occupied by a neutral molecule N- or O- donor Lewis base. The substitution of ligands on 6th coordination place was studied for mononuclear molybdenum(VI) complexes (1-8). Substitution reactions were performed both solvent-free and in solution. All prepared complexes were studied by infrared spectroscopy, chemical and thermal analysis and their structures were determined by X-ray crystallography.
