Abstract
U okviru ovog diplomskog rada opisana je sinteza kompleksa nikla(II) s tridentatnim hidrazonskim ligandima N'-(2-hidroksibenziliden)-4-hidroksibenzohidrazonom (SalHBOH), N'-(2- hidroksi-3-metoksibenziliden)-4-hidroksibenzohidrazonom (VanHBOH) i N'-(2-hidroksi-4- metoksibenziliden)-4-hidroksibenzohidrazonom (4-OMeSalHBOH). Oktaedarski kompleksi [Ni(HL)2] (1-3) dobiveni su direktnom reakcijom [Ni(OAc)2]∙4H2O i odgovarajućeg liganda pod specifičnim reakcijskim uvjetima. Korištenjem [MoO2(L)(EtOH)] kao prekursora i primjenom transmetalacije dobiveni su mononuklearni kompleksi [Ni(HSalHBOH)2]∙2MeOH (1), [Ni(HVanHBOH)2]∙MeOH (2) i organsko-anorganski hibridni spoj [Ni2(H4-OMeSalHBOH)2(CH3OH)4][Mo4O10(OCH3)6] (4). Dodatkom piridina priređeni su mononuklearni kompleksi s kvadratno-planarnom geometrijom [Ni(SalHBOH)(py)] (5), [Ni(VanHBOH)(py)] (6) i [Ni(4-OMeSalHBOH)(py)] (7). Produkti su identificirani kemijskom analizom, infracrvenom spektroskopijom i termogravimetrijskom analizom. Difrakcijom rentgenskog zračenja na monokristalnom uzorku određena je kristalna i molekulska struktura [Ni(HSalHBOH)2]∙2MeOH i [Ni2(H4-OMeSalHBOH)2(CH3OH)4] [Mo4O10(OCH3)6].
Abstract (english)
This thesis describes synthesis of nickel(II) complexes with tridentate hydrazone ligands N'- (2-hydroxybenzylidene)-4-hydroxybenzohydrazone (SalHBOH), N'-(2-hydroxy-3- methoxybenzylidene)-4-hydroxybenzohydrazone (VanHBOH) and N-(2-hydroxy-4- methoxybenzylidene)-4-hydroxybenzohydrazone (4-OMeSalHBOH). The octahedral complexes [Ni(HL)2] (1-3) are obtained by direct reaction of [Ni(OAc)2]∙4H2O and appropriate ligand under specific reaction conditions. Starting from [MoO2(L)(EtOH)] complexes as precursors and applying metal-exchange procedure, the mononuclear complexes [Ni(HSalHBOH)2]∙2MeOH (1), [Ni(HVanHBOH)2]∙MeOH (2) and hybrid organic-inorganic compound [Ni2(H4- OMeSalHBOH)2(CH3OH)4][Mo4O10(OCH3)6] (4) are achieved. When pyridine is used, mononuclear complexes with the square-planar geometry seems to be favoured as found for complexes [Ni(SalHBOH)(py)] (5), [Ni(VanHBOH)(py)] (6) and [Ni(4-OMeSalHBOH)(py)] (7). The resulting complex compounds are identified by means of the chemical analysis, infrared spectroscopy and thermogravimetric analysis. Crystal and molecular structures of [Ni(HSalHBOH)2]∙2MeOH and [Ni2(H4-OMeSalHBOH)2(CH3OH)4][Mo4O10(OCH3)6] are determined by the single crystal X-ray diffraction method.
