Title: Materials Data on Pr2ZrSe5 by Materials Project

Abstract

Pr2ZrSe5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pr3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Pr–Se bond distances ranging from 3.03–3.18 Å. Zr4+ is bonded to seven Se2- atoms to form distorted edge-sharing ZrSe7 pentagonal bipyramids. There are a spread of Zr–Se bond distances ranging from 2.68–2.87 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to four equivalent Pr3+ and one Zr4+ atom to form distorted SePr4Zr trigonal bipyramids that share corners with five equivalent SePr4Zr square pyramids, corners with five SePr4Zr trigonal bipyramids, corners with four equivalent SePr2Zr2 trigonal pyramids, edges with two equivalent SePr4Zr square pyramids, edges with four equivalent SePr4Zr trigonal bipyramids, and edges with four equivalent SePr2Zr2 trigonal pyramids. In the second Se2- site, Se2- is bonded to four equivalent Pr3+ and one Zr4+ atom to form distorted SePr4Zr trigonal bipyramids that share corners with four equivalent SePr4Zr square pyramids, corners with five SePr4Zr trigonal bipyramids, corners with four equivalent SePr2Zr2 trigonal pyramids, an edgeedge with one SePr4Zr square pyramid, edges with four equivalent SePr4Zr trigonal bipyramids, edges with four equivalent SePr2Zr2 trigonal pyramids, and amore » faceface with one SePr4Zr square pyramid. In the third Se2- site, Se2- is bonded to four equivalent Pr3+ and one Zr4+ atom to form distorted SePr4Zr square pyramids that share corners with nine SePr4Zr trigonal bipyramids, corners with eight equivalent SePr2Zr2 trigonal pyramids, edges with two equivalent SePr4Zr square pyramids, edges with three SePr4Zr trigonal bipyramids, edges with two equivalent SePr2Zr2 trigonal pyramids, and a faceface with one SePr4Zr trigonal bipyramid. In the fourth Se2- site, Se2- is bonded to two equivalent Pr3+ and two equivalent Zr4+ atoms to form distorted SePr2Zr2 trigonal pyramids that share corners with four equivalent SePr4Zr square pyramids, corners with four SePr4Zr trigonal bipyramids, corners with six equivalent SePr2Zr2 trigonal pyramids, an edgeedge with one SePr4Zr square pyramid, edges with four SePr4Zr trigonal bipyramids, and an edgeedge with one SePr2Zr2 trigonal pyramid.« less
