Cerous sodium nitrate monohydrate, Na2Ce(NO3)5·H2O

Nathalie Audebrand, D. Louër

Open publisher page 4 citations

Abstract

The title compound, disodium cerium pentanitrate monohydrate, was synthesized from a nitric acid solution of Ce(NO(3))(3).6H(2)O and NaNO(3), and its structure has been determined from single-crystal X-ray diffraction data. The structure is built from isolated chains of irregular icosahedral [Ce(NO(3))(6)](3-) anions. Na atoms and water molecules are located between the chains. The Na coordination polyhedra, in the form of a square antiprism or a monocapped square antiprism, share common vertices and contribute to the formation of a three-dimensional network. Ten nitrate groups act as bridging ligands.
