Abstract

Ovaj diplomski rad sastoji se od dvije cjeline: istraživačkog i metodičkog dijela. U
istraživačkom dijelu sintetiziran je niz kadmijevih(II) koordinacijskih polimera s 2-
kloropirazinom (2-Clpz), 2-bromopirazinom (2-Brpz) i 2-jodopirazinom(2-Ipz) s raznim
halogenidnim anionima kao protuionima.
Kristalne strukture kompleksa [CdBr2(2-Clpz)2]n, [CdBr2(2-Brpz)2]n, [CdI2(2-Brpz)2]n,
[CdI2(2-Ipz)2]n određene su rentgenskom strukturnom analizom. Kompleksi su
okarakterizirani IR spektroskopijom,... More metodom rentgenske difrakcije u polikristalnom
uzorku, termogravimetrijskom analizom i diferencijalnom skenirajućom kalorimetrijom.
Ustanovljeno je da se najbliži polimerni lanci međusobno povezuju halogenskim
interakcijama između halogenog atoma halopirazinskog liganda i halogenidnog iona
vezanog na kadmijev(II) kation neoivsno o halogenom atomu te halogenidnom ionu.
U metodičkom dijelu rada pod naslovom „Kemijska svojstva alkohola – primjer dobre
nastavne prakse“, metodički je preoblikovan pokus pomoću kojeg se principi „zelene
kemije“ integriraju u nastavni proces. Predložen je nastavni dvosat učenja otkrivanjem u
kojem su ciljana obrazovna postignuća za uzrast učenika četvrtog razreda gimnazije
povezana s opažanjima iz pokusa. Less

Abstract (english)

This Diploma thesis consists of two parts: the research part and the methodological part.
In the research part a series of cadmium(II) coordination polymers was prepared with 2-
chloropyrazine (2-Clpz), 2-bromopyrazine (2-Brpz) and 2-iodopyrazine (2-Ipz) and
halide anions as counter ions.
The crystal structures of the complexes [CdBr2(2-Clpz)2]n, [CdBr2(2-Brpz)2]n, [CdI2(2-
Brpz)2]n, [CdI2(2-Ipz)2]n were determined by single crystal Xray structural analysis. The
complexes were studied... More by infrared spectroscopy, PXRD methods, thermal analysis and
differential scanning calorimetry. Crystal structure analysis revealed that the closest
polymeric chains are interconnected via halogen interactions between halogen atoms and
halide ions coordinated on metal centers regardless of the halogen atom and halide ions.
In the methodological part of the Thesis entitled „Chemical properties of alcohols – an
example of good teaching practice" one experiment was methodically transformed with
integrated principles of „green chemistry“. Two hour discovery lesson was suggested, in
which the targeted educational achievement for students of the fourth year of high school
are associated with the observations from the experiment. Less
