KINALDINSKA KISLINA KOT KATION V NEKATERIH FLUORIDOMETALATNIH SOLEH

Lukšič, Andraž (author), Pevec, Andrej (mentor)

Delo temelji na sintezi in karakterizaciji spojin kinaldinske kisline in nekaterih fluoridometalatov: heksafluoridosilikatov(IV), heksafluoridotitanatov(IV) in pentafluoridooksidovanadatov(V). Za vsak fluoridometalat so bile opravljene tri sintezne reakcije med kinaldinsko kislino in ustreznim oksidom v razmerju 1:2, 1:1 in 1:0,5. Vse reakcije so potekale v vodni raztopini fluorovodikove kisline. Produkti reakcij so bili analizirani z infrardečo spektroskopijo, nuklearno magnetno resonančno spektroskopijo, elementno analizo in rentgensko strukturno analizo. S pomočjo rentgenske strukturne analize sta opisani kristalni strukturi dveh spojih, ki doslej še nista bili objavljeni: 2-karboksikinolinijev fluorid in 2-karboksikinolinijev heksafluoridotitanat.

• Title: QUINALDIC ACID AS CATION IN SOME FLUORIDOMETALATE SALTS

Abstract

A research is based on a synthesis and characterization of quinaldic acid and some fluoridometalate compounds [hexafluoridosilicate(IV), hexafluoridotitanate(IV) and pentafluoridooxidovanadate(V)]. Three synthesis reactions between quinaldic acid and the corresponding oxide were carried out for each fluoridometalate in a stoichiometric ratio of 2:1, 1:1 and 0.5:1. All reactions were carried out in aqueous hydrofluoric acid solution. Reaction products were analysed by infrared spectroscopy, nuclear magnetic resonance spectroscopy, elemental analysis and X-ray structural analysis. Two unpublished novel compounds, namely 2-carboxyquinolinium fluoride and 2-carboxyquinolinium hexafluorotitanate, were described by the X-ray structural analysis.
