Kromove spojine s pirazinojsko kislino

diplomsko delo

Tjaša Granda (Author), Saša Petriček (Mentor)

Abstract

Izvedli smo več reakcij med kromovim kloridom heksahidratom in pirazinojsko kislino v različnih topilih ali mešanicah le teh. V nekaterih primerih smo v reakcijsko zmes dodali še koncentrirano HCl. Reakcije so potekale pri sobni temperaturi ali na oljni kopeli pri temperaturi 60 °C. Nastali so temno zeleni kristali dveh koordinacijskih spojin [CrCl$_2$(pyza)(pyzaH)]·2H$_2$O in [Cr(pyza)$_3$]·nH$_2$O. Vse nastale produkte smo analizirali z IR spektroskopijo. Za dodatno potrditev sestave nastalih produktov smo uporabili še CHN analizo, termično analizo in rentgensko praškovno difrakcijo.

Secondary title:	Chromium compounds with pyrazinoic acid
Secondary abstract:	Several reactions between chromium chloride hexahydrate and pyrazinoic acid were carried out in various solvents or their mixtures. In some cases, concentrated HCl was added to the reaction mixture. The reactions were conducted at room temperature or in an oil bath at 60 °C. Dark green crystals of two coordination compounds, [CrCl$_2$(pyza)(pyzaH)]·2H$_2$O and [Cr(pyza)$_3$]·nH$_2$O, were formed. All resulting products were analyzed by IR spectroscopy. To further confirm the composition of the products, CHN analysis, thermal analysis, and powder X-ray diffraction were also employed.
