Abstract

Pr2(FeSb)O7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded to eight O2- atoms to form distorted PrO8 hexagonal bipyramids that share edges with two equivalent PrO8 hexagonal bipyramids, edges with two equivalent FeO6 octahedra, and edges with four equivalent SbO6 octahedra. There are a spread of Pr–O bond distances ranging from 2.28–2.62 Å. In the second Pr3+ site, Pr3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.31–2.62 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with four equivalent SbO6 octahedra, and edges with two equivalent PrO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 48–50°. There are two shorter (2.06 Å) and four longer (2.10 Å) Fe–O bond lengths. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra, corners with four equivalent FeO6 octahedra, and edges with four equivalent PrO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 46–48°. There are four shortermore »« less
