Abstract
A new iron(III) phosphate, RbFe(HPO4)2, has been synthesised hydrother mally at 230-degrees-C and characterized by single-crystal X-ray diffr action. The crystal is trigonal with a very long c axis: space group R 3cBAR, a = 8.160(1), c = 52.75(1) angstrom, z = 18 and R = 0.0207. The compound adopts an intersecting tunnel structure, with the rubidium c ations in the tunnels. The framework consists of corner-sharing FeO6 o ctahedra and HPO4 groups. A triclinic polymorph was also obtained.
