Materials Data on Sr2Pr2PtO6 by Materials Project

Abstract

Sr2Pr2PtO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent O2- atoms to form distorted SrO6 octahedra that share corners with three equivalent PtO6 octahedra, corners with nine equivalent PrO6 octahedra, edges with three equivalent SrO6 octahedra, a faceface with one PrO6 octahedra, and a faceface with one PtO6 octahedra. The corner-sharing octahedra tilt angles range from 37–60°. There are three shorter (2.53 Å) and three longer (2.59 Å) Sr–O bond lengths. Pr3+ is bonded to six equivalent O2- atoms to form distorted PrO6 octahedra that share corners with nine equivalent SrO6 octahedra, edges with three equivalent PrO6 octahedra, edges with three equivalent PtO6 octahedra, and a faceface with one SrO6 octahedra. The corner-sharing octahedra tilt angles range from 37–60°. There are three shorter (2.37 Å) and three longer (2.57 Å) Pr–O bond lengths. Pt2+ is bonded to six equivalent O2- atoms to form PtO6 octahedra that share corners with six equivalent SrO6 octahedra, edges with six equivalent PrO6 octahedra, and faces with two equivalent SrO6 octahedra. The corner-sharing octahedral tilt angles are 40°. All Pt–O bond lengths are 2.39 Å. O2- is bonded to two equivalent Sr2+, two equivalent Pr3+, and one Pt2+ atom to form a mixture of distorted edge and corner-sharing OSr2Pr2Pt trigonal bipyramids.
