Iridium (IV) fluoride is a chemical compound of iridium from the group of fluorides .
Extraction and presentation
Iridium (IV) fluoride can be obtained by reacting iridium (VI) fluoride with sulfur , metals or other halogens.
properties
Iridium (IV) fluoride is a red solid. In humid air it decomposes, swelling and turning red. In water it hydrolyzes instantly with strong heat development and formation of iridium (IV) oxide dihydrate and hydrogen fluoride . It is reduced to lower fluorides by reducing agents when heated. It has an orthorhombic crystal structure with the space group Fdd 2 (space group no. 43) and is paramagnetic .
