Ammonium cerium(IV) sulfate is an inorganic compound with the formula (NH4)4Ce(SO4)4.2 H2O. 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.


A crystallographic study shows that the compound contains the Ce2(SO4)88− anion, where the cerium atoms are 9 coordinated by oxygen atoms belonging to sulfate groups, in a distorted tricapped trigonal prism.[1]
