Uranium (VI) chloride is a chemical compound of uranium from the group of chlorides .
presentation
Uranium (VI) chloride can be obtained by decomposing uranium (V) chloride at 175 ° C.
It can also be prepared by reacting uranium (VI) fluoride with an excess of boron trichloride at −196 ° C.
properties
Uranium (VI) chloride is a black-green, very hygroscopic , crystalline solid. It slowly decomposes at temperatures above 120 ° C. It reacts with liquid hydrogen fluoride or uranium (VI) fluoride to form uranium (IV) fluoride and uranium (V) fluoride . It reacts with carbon tetrachloride to form uranium (V) chloride. It has a trigonal crystal structure with the space group P 3 m 1 (No. 164) .
