Abstract

Ovaj rad se sastoji od istraživačkog i metodičkog dijela. U sklopu istraživačkog dijela diplomskog rada istražena je mogućnost nastajanja koordinacijskih spojeva bakra(II) s imidazolom i odabranom organskom kiselinom i s derivatom imidazola i odabranom organskom kiselinom, koristeći različite omjere i koncentracije tvari. U tu svrhu proveden je niz otopinskih sintetskih reakcija. Dobiveni produkti analizirani su difrakcijom rendgenskog zračenja na polikristalnom uzorku i infracrvenom spektroskopijom. Za tri produkta za koje su dobiveni kvalitetni jedinični kristali, određena je kristalna i molekulska struktura metodom difrakcije rendgenskog zračenja na jediničnom kristalu, čime je utvrđeno da su nastali spojevi [Cu(Him)2(adi)], [Cu(Him)2(Hadi)2] i [Cu2(im)2(adi)]. U metodičkom dijelu diplomskog rada istražen je povijesni razvoj poučavanja kemije u hrvatskim školama od 17. stoljeća do danas. Pregled obuhvaća razvoj sadržaja i temeljnih kemijskih pojmova kroz dostupnu udžbeničku literaturu. U radu su predložene mogućnosti integriranja povijesnog razvoja odabranog pojma u suvremenu nastavnu praksu.

Abstract (english)

This diploma thesis consists of two parts: the research part and the methodological part. Within the research part of the thesis, the possibility of forming coordination compounds of copper(II) with imidazole and a selected organic acid, and also with an imidazole derivative and a selected organic acid, using different ratios and concentrations of substances was investigated. For this purpose, a number of in solution synthetic reactions were tested. The obtained products were analyzed by X-ray diffraction on polycrystalline samples and infrared spectroscopy. For three products that yielded high-quality single crystals, the crystal and molecular structure was determined using the single crystal X-ray diffraction method, establishing that the formed compounds were [Cu(Him)2(adi)], [Cu(Him)2(Hadi)2] and [Cu2(im)2(adi)]. In the methodological part of the thesis, the historical development of teaching chemistry in Croatian schools from the 17th century to the present day was explored. The review covers the development of content and basic chemical concepts through the available textbook literature. In the thesis, the possibilities of integrating the historical development of the chosen concept into contemporary teaching practice are proposed.
