Abstract

Ovaj diplomski rad sastoji se od dvije cjeline: istraživačkog i metodičkog dijela. U
istraživačkom dijelu rada ukupno je priređeno 5 novih spojeva kadmijevih(II) halogenida s 3-
aminopiridinskim ligandima [Cd(μ-Cl)(μ3-Cl)(3-NH2py)]n : [Cd(μ-Cl)2(3-NH2py)2]n (1a),
[Cd(μ-Br)2(μ-3-NH2py)2]n (2a), [CdI2(3-NH2py)2] (3), [CdCl2(3-NH2py)4]·EtOH (X = Cl, Br;
1b, 2b). Također su priređena tri literaturno poznata spoja s 4-aminopirdinskim ligandima
[CdX2(4-NH2py)2]n (X = Cl, Br, I; 4-6) u svrhu ispitivanje njihovih mehaničkih svojstava. Za
karakterizaciju priređenih spojeva korištena je difrakcija rendgenskog zračenja u polikristalnom
uzorku i infracrvena spektroskopija. Spojevima 1a, 1b, 2a, 2b i 3 određena je kristalna struktura
metodom difrakcije rendgenskog zračenja u jediničnom kristalu. Preliminarna ispitivanja
mehaničkog odziva provedena su na kristalima spojeva 2a, 3, 4, 5 koji su bili odgovarajuće
morfologije i zadovoljavajuće kvalitete.
U metodičkom dijelu rada načinjen je pregled i kritički osvrt stručne literature na temu Fazni
dijagram. Predložen je 90-minutni nastavni sat učenja otkrivanjem u kojemu su ciljana
obrazovna postignuća primjerena za uzrast učenika prvog razreda gimnazije te je detaljno
razrađen radni listić za učenike kao i uputa za nastavnika.

Abstract (english)

This thesis consists of two parts: research and methodological parts. In the research part, five
new compounds of cadmium(II) halides with 3-aminopyridine ligands were prepared
[Cd(μ-Cl)(μ3-Cl)(3-NH2py)]n : [Cd(μ-Cl)2(3-NH2py)2]n (1a), [Cd(μ-Br)2(μ-3-NH2py)2]n (2a),
[CdI2(3-NH2py)2] (3), [CdCl2(3-NH2py)4]·EtOH (X = Cl, Br; 1b, 2b), along with three
compounds with 4-aminopyridine ligands which are previously known from literature [CdX2(4-
NH2py)2]n (X = Cl, Br, I; 4-6). Diffraction of X-ray radiation in polycrystalline sample (PXRD)
and infrared spectroscopy (IR) were used to characterize the prepared compounds. The crystal
structure of compounds 1a, 1b, 2a, 2b and 3 was determined using single crystal X-ray
diffraction. Preliminary investigations of the mechanical properties of crystals were carried out
on crystals of compounds 2a, 3, 4, 5 with appropriate morphology and satisfactory quality.
In the methodological part of the paper, an overview and critical review of professional
literature on the topic Phase diagram was made. A 90-minute learning lesson has been proposed
by disclosure in which targeted educational achievements are appropriate for the age of first-
graders of the gymnasium and a worksheet for students as well as instructions for teacher have
been elaborated in detail.
