Title: Materials Data on Ce4SiI5 by Materials Project

Abstract

Ce4SiI5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded to one Si and five I atoms to form a mixture of distorted edge and corner-sharing CeSiI5 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. The Ce–Si bond length is 2.84 Å. There are a spread of Ce–I bond distances ranging from 3.19–3.68 Å. In the second Ce site, Ce is bonded to two equivalent Si and four I atoms to form a mixture of edge and corner-sharing CeSi2I4 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. Both Ce–Si bond lengths are 2.92 Å. There are a spread of Ce–I bond distances ranging from 3.24–3.40 Å. Si is bonded to six Ce atoms to form edge-sharing SiCe6 octahedra. There are three inequivalent I sites. In the first I site, I is bonded in a distorted see-saw-like geometry to four Ce atoms. In the second I site, I is bonded in a distorted T-shaped geometry to three Ce atoms. In the third I site, I is bonded in a square co-planar geometry to four equivalent Ce atoms.
