Title: Materials Data on Cs4Pr6C2I13 by Materials Project

Abstract

Cs4Pr6C2I13 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Cs is bonded in a 7-coordinate geometry to seven I atoms. There are a spread of Cs–I bond distances ranging from 3.98–4.27 Å. There are two inequivalent Pr sites. In the first Pr site, Pr is bonded to one C and five I atoms to form distorted PrCI5 octahedra that share a cornercorner with one PrCI5 octahedra, corners with two equivalent PrC2I5 pentagonal bipyramids, and edges with four equivalent PrC2I5 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 0°. The Pr–C bond length is 2.31 Å. There are a spread of Pr–I bond distances ranging from 3.18–3.42 Å. In the second Pr site, Pr is bonded to two equivalent C and five I atoms to form distorted PrC2I5 pentagonal bipyramids that share a cornercorner with one PrCI5 octahedra, edges with two equivalent PrCI5 octahedra, edges with two equivalent PrC2I5 pentagonal bipyramids, and faces with two equivalent PrC2I5 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 7°. There are one shorter (2.63 Å) and one longer (2.64 Å) Pr–C bond lengths. There are a spread of Pr–I bond distances ranging from 3.20–3.46 Å. C is bonded in a 6-coordinatemore » geometry to five Pr and one C atom. The C–C bond length is 1.39 Å. There are four inequivalent I sites. In the first I site, I is bonded to two equivalent Cs and three Pr atoms to form distorted ICs2Pr3 trigonal bipyramids that share corners with three equivalent ICs2Pr3 trigonal bipyramids, an edgeedge with one ICs2Pr3 trigonal bipyramid, and a faceface with one ICs4Pr2 octahedra. In the second I site, I is bonded to four equivalent Cs and two equivalent Pr atoms to form face-sharing ICs4Pr2 octahedra. In the third I site, I is bonded in a 5-coordinate geometry to two equivalent Pr atoms. In the fourth I site, I is bonded in a 6-coordinate geometry to four equivalent Cs and two Pr atoms.« less
