Title: Materials Data on CeSi2Ni9 by Materials Project

Abstract

CeNi9Si2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Ce is bonded in a 10-coordinate geometry to eighteen Ni and four equivalent Si atoms. There are a spread of Ce–Ni bond distances ranging from 3.01–3.17 Å. All Ce–Si bond lengths are 3.36 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 2-coordinate geometry to two equivalent Ce, eight equivalent Ni, and four equivalent Si atoms. All Ni–Ni bond lengths are 2.60 Å. All Ni–Si bond lengths are 2.56 Å. In the second Ni site, Ni is bonded to two equivalent Ce, eight Ni, and two equivalent Si atoms to form a mixture of distorted edge, corner, and face-sharing NiCe2Si2Ni8 cuboctahedra. There are a spread of Ni–Ni bond distances ranging from 2.41–2.58 Å. There are one shorter (2.32 Å) and one longer (2.36 Å) Ni–Si bond lengths. Si is bonded in a 12-coordinate geometry to two equivalent Ce and ten Ni atoms.
