Abstract

U ovom diplomskom radu istražene su reakcije oksobis(pentan-2,4-dionato)vanadija(IV) i salicilaldehid izonikotinoil hidrazona (H2SIH), odnosno salicilaldehid nikotinoil hidrazona (H2SalNH) s metanolom, etanolom i propanolom. U reakcijama s ligandom H2SIH sintetizirani su tetramer [VO(SIH)(MeO)]44CH3OH, monomer [VO2(HSIH)] i polimer [VO(SIH)(PrO)]n. Reakcijama između oksobis(pentan-2,4-dionato)vanadija(IV) i H2SalNH u metanolu, etanolu i propanolu sintetizirani su monomer [VO(SalNH)(OMe)(HOMe)] te polimeri [VO(SalNH)(OEt)]n i [VO(SalNH)(OPr)]n. Spojevi su identificirani na temelju podataka dobivenih infracrvenom spektroskopijom, termogravimetrijskom analizom, difrakcijom rentgenskog zračenja na jediničnom kristalu te u polikristalnom uzorku.

Abstract (english)

In this thesis, the reactions of oxobis(pentan-2,4-dionato)vanadium(IV) with salicylaldehyde isonicotinoyl hydrazone (H2SIH) and salicylaldehyde nicotinoyl hydrazone (H2SalNH) with methanol, ethanol, and propanol were investigated. In the reactions with the H2SIH ligand, the tetramer [VO(SIH)(MeO)]4·4CH3OH, the monomer [VO2(HSIH)], and the polymer [VO(SIH)(PrO)]n were synthesized. Reactions between oxobis(pentan-2,4- dionato)vanadium(IV) and H2SalNH in methanol, ethanol, and propanol yielded the monomer [VO(SalNH)(OMe)(HOMe)] and the polymers [VO(SalNH)(OEt)]n and [VO(SalNH)(OPr)]n. The compounds were identified based on data obtained from infrared spectroscopy, thermogravimetric analysis, single-crystal X-ray diffraction, and powder X-ray diffraction
