Adenin kot kation v heksafluoridosilikatnih soleh

Brulc, Rok (author), Pevec, Andrej (mentor)

V diplomskem delu opisujem sintezo heksafluoridosilikatne soli s formulo [RH2]2+[SiF6]2- (1), v kateri je R adenin. Pri sintezi so bili kot reaktanti uporabljeni: SiO2, fluorovodikova kislina in adenin. Reakcija je bila izvedena v stehiometričnem razmerju 1 : 1 med SiO2 in adeninom, kar je vodilo do nastanka dvoprotoniranega adeninskega kationa. Iz raztopine fluorovodikove kisline so se izločili kristali, ki so bili nato analizirani z rentgensko strukturno analizo. Nastali produkt sem strukturno primerjal s spojino [RH]2+[SiF6]2- (R = adenin) (2) z že znano strukturo, ki vsebuje enoprotoniran adeninski kation.

• Title: Adenine as cation in hexafluoridosilicate

Abstract

In this thesis I describe the synthesis of hexafluoridosilicate salt with formula [RH2]2+[SiF6]2-(1), where R is adenine. SiO2, hydrofluoric acid and adenine were used as reactants in the synthesis. The reaction was performed in a stoichiometric ratio of 1 : 1 between SiO2 and adenine, which led to the formation of a double-protonated adenine cation. Crystals were formed in hydrofluoric acid solution, which were then analyzed by X–ray crystallography. The structure of resulting product was compared with compound [RH]2+[SiF6]2- (R = adenine) (2) with known structure containing a monoprotonated adenine cation.
