FLUORIDOOKSIDOVANADATI NEKATERIH HALOPIRIDINOV

Benda, Klavdija (author), Pevec, Andrej (mentor)

V okviru diplomskega dela sem izvedla večje število različnih reakcij med vanadijevim(V) oksidom in ustreznim halopiridinom v fluorovodikovi kislini. Halopiridini, ki sem jih uporabila so bili: 2-fluoropiridin, 2-kloropiridin ter 2-bromopiridin. Nastali sta dve novi spojini: 2-kloropiridinijev akvatetrafluoridooksidovanadat(V), (C5H5NCl)[VOF4(H2O)] in 2-bromopiridinijev akvatetrafluoridooksidovanadat(V), (C5H5NBr)[VOF4(H2O)]. Nastale produkte sem okarakterizirala s pomočjo elementne analize, infrardeče spektroskopije, 1H in 19F nuklearne magnetne resonančne spektroskopije in rentgenske strukturne analize. Halopiridinijevi kationi C5H5NX+ (X = Cl, Br) in akvatetrafluoridooksidovanadatni(V) anioni [VOF4(H2O)]- so v nastalih trdnih produktih med seboj povezani z vodikovimi vezmi.

Abstract

A number of different reactions between vanadium(V) oxide and corresponding halopyridine in hydrofluoric acid have been carried out. Halopyridines that I used are: 2-fluoropyridine, 2-chloropyridine and 2-bromopyridine. Two new compounds were obtained: 2-chloropyridinium aquatetrafluoridooksidovanadate(V), (C5H5NCl)[VOF4(H2O)] and 2-bromopyridinium aquatetrafluoridooksidovanadate(V), (C5H5NBr)[VOF4(H2O)]. The resulting products were characterized by elemental analysis, infrared spectroscopy, 1H and 19F nuclear magnetic resonance spectroscopy and X-ray structural analysis. Halopyridinium cations C5H5NX+ (X = Cl, Br) and aquatetrafluoridooxidovanadate(V) anions [VOF4(H2O)]- are connected by hydrogen bonds in solid products.
