Preparation, Properties, and Structure
The anion 2− is generated by dissolving Ce2O3 in hot concentrated HNO3.
This salt consists of the anion 2− and a pair of NH4+ counter ions. The ammonium ions are not involved in the oxidising reactions of this salt. In the anion each nitrato group is chelated to the cerium atom in a bidentate manner as shown below:
The anion 2− has idealized Oh molecular symmetry. The CeO12 core defines an icosahedron.

Famous quotes containing the word structure:
“Communism is a proposition to structure the world more reasonably, a proposition for changing the world. As such, we have to analyze it and, if we deem it reasonable, act upon it.”
—Friedrich Dürrenmatt (1921–1990)
