Caesium sodium bis(formate)

N. W. Alcock, M. P. Wilson and P. M. Rodger

Abstract: The title compound, CsNa(CHO₂)₂, was obtained from the crystallization of caesium formate in a glass container. It has a complex structure, with sodium ions octahedrally coordinated and caesium ions irregularly eight-coordinated by the formate O atoms. One Cs cation and four formate C atoms have site symmetry m and one Na cation has site symmetry $\\overline{1}$ , resulting in the unusual situation of Z = 12 for an orthorhombic structure.
