Materials Data on GdSi2Ni by Materials Project

Abstract

GdNiSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd is bonded in a 4-coordinate geometry to four equivalent Ni and ten Si atoms. All Gd–Ni bond lengths are 3.04 Å. There are a spread of Gd–Si bond distances ranging from 3.00–3.07 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Gd and five Si atoms. There are a spread of Ni–Si bond distances ranging from 2.23–2.29 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to six equivalent Gd, one Ni, and two equivalent Si atoms. Both Si–Si bond lengths are 2.35 Å. In the second Si site, Si is bonded in a 12-coordinate geometry to four equivalent Gd and four equivalent Ni atoms.
