Abstract

Hidrazonski ligandi i njihovi koordinacijski spojevi imaju široku primjenu u biološkom,
farmaceutskom, analitičkom, katalitičkom i industrijskom području. Pripravljena su dva
hidrazonska liganda, derivati 2-hidroksi-3-metoksibenzaldehida s hidrazidom mravlje kiseline
(H2L1) ili hidrazidom octene kiseline (H2L2). Molibdenski hidrazonski kompleksi pripravljeni
su reakcijom [MoO2(acac)2] (gdje je acac oznaka za acetilacetonat) s navedenim ligandima.
Novonastali hidrazonski ligandi (H2L1 i H2L2) te mononuklearni i polinuklearni
molibdenski(VI) kompleksi su sintetizirani i okarakterizirani spektroskopskim metodama
(IR‒ATR, NMR). Njihovo termičko ponašanje okarakterizirano je termogravimetrijskom
analizom. Kristalne i molekulske strukture liganda H2L1 i H2L2, mononuklearnih kompleksa
[MoO2(L1)(H2O)], [MoO2(L2)(H2O)], [MoO2(L2)(MeOH)] te spoj (Hpy)2Mo8O26 određeni su
difrakcijom rendgenskog zračenja na jediničnom kristalu. Također, ispitani su putevi sinteze
kompleksa molibdena(V).

Abstract (english)

Hydrazone ligands and their metal complexes have wide applications in biological,
pharmaceutical, analytical, catalytic, and industrial fields. Two hydrazone ligands were
prepared, derivatives of 2-hydroxy-3-methoxybenzaldehyde with formic acid hydrazide (H2L1)
and acetic acid hydrazide (H2L2). Molybdenum hydrazone complexes were prepared by the
reaction of [MoO2(acac)2] (where acac is the symbol for acetylacetonate) with hydrazone
ligands. New hydrazone ligands (H2L1 and H2L2), mononuclear and polynuclear
molybdenum(VI) complexes were synthesized and characterized by spectroscopic methods
(IR‒ATR, NMR). Their thermal behaviour was characterized by thermogravimetric analysis.
Crystal and molecular structures of ligands H2L1 and H2L2, mononuclear complexes
[MoO2(L1)(H2O)], [MoO2(L2)(H2O)], [MoO2(L2)(MeOH)] and compound (Hpy)2Mo8O26 were
determined by single crystal X‒ray diffraction. Also, the synthesis of molybdenum(V)
complexes was explored.
