RbZnFe(PO4)2: synthesis and crystal structure

Abstract

A new iron phosphate, rubidium zinc iron(III) phosphate, RbZnFe(PO4)2, has been synthesized as single crystals by the flux method. This compound is isostructural to the previously reported KCoAl(PO4)2[Chenet al.(1997).Acta Cryst.C53,1754–1756]. Its structure consists of a three-dimensional framework built up from corner-sharing PO4and (Zn,Fe)O4tetrahedra. This mode of linkage forms channels parallel to the [100], [010] and [001] directions in which the Rb+ions are located.
