Synthesis and crystal structure of cerium(IV) bis­(phosphite)

The structure of cerium(IV) bis­(phosphite), Ce(HPO(3))(2), has been solved by single-crystal X-ray diffraction and has trigonal (P-3m1) symmetry. The cerium(IV) cation exhibits site symmetry -3m. and is octa­hedrally coordinated by O atoms of the phosphite ligands (point group symmetry 3m.). The hi...

Sumario:The structure of cerium(IV) bis­(phosphite), Ce(HPO(3))(2), has been solved by single-crystal X-ray diffraction and has trigonal (P-3m1) symmetry. The cerium(IV) cation exhibits site symmetry -3m. and is octa­hedrally coordinated by O atoms of the phosphite ligands (point group symmetry 3m.). The highly symmetrical compound has a layered structure parallel to the ab plane, and is closely related to zirconium(IV) bis­(phosphite) solved via powder X-ray diffraction with trigonal (P-3 symmetry. Structural details of the two compounds are comparatively discussed.
