Materials Data on RbFeCu(PO4)2 by Materials Project
Abstract
RbFeCu(PO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.19 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra and corners with two equivalent CuO5 trigonal bipyramids. There are a spread of Fe–O bond distances ranging from 1.95–2.25 Å. Cu2+ is bonded to five O2- atoms to form CuO5 trigonal bipyramids that share corners with two equivalent FeO6 octahedra, corners with three PO4 tetrahedra, an edgeedge with one PO4 tetrahedra, and an edgeedge with one CuO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 51–61°. There are a spread of Cu–O bond distances ranging from 1.94–2.27 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent FeO6 octahedra and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 36–38°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+ is bonded to fourmore »
