Ksantin kot ligand v koordinacijskih spojinah

Levstek, Jaka (author), Pevec, Andrej (mentor)

Izvedel sem reakcije med ligandom ksantinom in kovinskimi ioni prehoda, kot so Ni(II), Co(II), Cu(II), Cd(II), Zn(II) in Pb(II), ob dodatku KSCN. Reakcije so bile izvedene v metanolu in vodi s segrevanjem na oljni kopeli. Pri dveh reakcijah je nastala koordinacijska spojina, v eni so se na cinkov ion koordinirali štirje tiocianatni ioni, v drugi pa so se na cinkov ion koordinirali štirje ligandi, dve molekuli ksantina in dva kloridna iona. Obe spojini sta že opisani v literaturi. Nastale kristalinične produkte sem analiziral z IR spektroskopijo, 1H NMR spektroskopijo in rentgensko strukturno analizo.

Abstract

This bachelor’s thesis describes different reactions between the ligand xanthine and transition metal ions such as Ni(II), Co(II), Cu(II), Cd(II), Zn(II) and Pb(II) with the addition of KSCN. The reactions were carried out in methanol and water by using an oil bath. Two of the reactions produced a coordination compound, in one four thiocyanate ions coordinated around the zinc, in the other two xanthine molecules coordinated around the zinc along two chloride ions. Both compounds have already been described in the literature. The resulting crystalline products were analyzed by IR spectroscopy, 1H NMR spectroscopy and X-ray structural analysis.
