'''Ammonium cerium(IV) sulfate |
'''Ammonium cerium(IV) sulfate''' is an [[inorganic compound]] with the formula (NH<sub>4</sub>)<sub>4</sub>Ce(SO<sub>4</sub>)<sub>4</sub>·2H<sub>2</sub>O. It is an orange-colored solid. It is a strong oxidant, the potential for reduction is about +1.44V. [[Cerium(IV) sulfate]] is a related compound. |
||
==Structure== |
|||
Ammonium cerium(IV) sulfate is a very safe oxidizer, one of the most nontoxic ones. |
|||
A crystallographic study shows that the compound contains the Ce<sub>2</sub>(SO<sub>4</sub>)<sub>8</sub><sup>8−</sup> anion, where the cerium atoms are 9 coordinated by oxygen atoms belonging to sulfate groups, in a distorted tricapped trigonal prism. The compound is thus sometimes formulated as (NH<sub>4</sub>)<sub>8</sub>[Ce<sub>2</sub>(SO<sub>4</sub>)<sub>8</sub>]·4H<sub>2</sub>O.<ref name="ShanHuang1998">{{cite journal|last1=Shan|first1=Y.|last2=Huang|first2=S.
