Title: Materials Data on Ba2PrIrO6 by Materials Project

Abstract

Ba2PrIrO6 crystallizes in the tetragonal P4/mnc space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent PrO6 octahedra, and faces with four equivalent IrO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.93–3.19 Å. Pr3+ is bonded to six O2- atoms to form PrO6 octahedra that share corners with six equivalent IrO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. There are four shorter (2.33 Å) and two longer (2.34 Å) Pr–O bond lengths. Ir5+ is bonded to six O2- atoms to form IrO6 octahedra that share corners with six equivalent PrO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. All Ir–O bond lengths are 1.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one Pr3+, and one Ir5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Pr3+, and onemore » Ir5+ atom.« less
