Abstract

U ovom diplomskom radu ispitani su uvjeti nastajanja kompleksa molibdena(VI) s derivatima
2-aminobenzhidrazida koji sadrže O i N donorne atome. Provedene su reakcije H2Sal-2-
HBNH2 (2-amino-N'-[(2-hidroksifenil)metiliden]benzhidrazid), H2Van-2-HBNH2 (2-amino-
N'-(2-hidroksi-3-metoksibenziliden)benzhidrazid) i H24OMeSal-2-HBNH2 (2-amino-N'-(2-
hidroksi-4-metoksibenziliden)benzhidrazid) s bis(pentan-2,4-dionato)dioksomolibdenom(VI)
pri različitim temperaturama u metanolu i acetontrilu te su priređeni kompleksi [MoO2(Sal-2-
HBNH2)(MeOH)], [MoO2(Sal-2-HBNH2)]2 (forma I i forma II), [MoO2(Van-2-HBNH2)]2,
[MoO2(4OMeSal-2-HBNH2)(MeOH)], [MoO2(4OMeSal-2-HBNH2)]2 i [MoO2(Sal-2-
HBNH2)]2∙2CH3CN. Svi produkti okarakterizirani su IR spektroskopijom, klasičnom
kemijskom analizom, termičkom analizom te difrakcijom rentgenskog zračenja na
polikristalnom uzorku. Molekulska i kristalna struktura određena je difrakcijom rentgenskog
zračenja na monokristalnom uzorku za sve spojeve osim [MoO2(Van-2-HBNH2)]2.

Abstract (english)

In this Diploma Thesis synthesis conditions to obtain molybdenum(VI) complexes with 2-
aminobenzhydrazide derivatives containing O and N donor atoms were studied. The reactions
of H2Sal-2-HBNH2 (2-amino-N'-[(2-hydroxyphenyl)methylidene]benzhydrazide), H2Van-2-
HBNH2 (2-amino-N'-(2-hydroxy-3-methoxybenzylidene)benzhydrazide) and H24OMeSal-2-
HBNH2 (2-amino-N'-(2-hydroxy-4-methoxybenzylidene)benzhydrazide) with bis(pentan-2,4-
dionato)dioxomolybdenum(VI) were carried out at various temperatures in methanol and
acetonitrile, and following complexes were prepared: [MoO2(Sal-2-HBNH2)(MeOH)],
[MoO2(Sal-2-HBNH2)]2 (form I i form II), [MoO2(Van-2-HBNH2)]2, [MoO2(4OMeSal-2-
HBNH2)(MeOH)], [MoO2(4OMeSal-2-HBNH2)]2 i [MoO2(Sal-2-HBNH2)]2∙2CH3CN. All
products were characterized by IR spectroscopy, classic chemical analysis, thermal analysis
and X-ray powder diffraction. Molecular and crystal structure was determined by the singlecrystal
X-ray diffraction for all compounds except for [MoO2(Van-2-HBNH2)]2.
