Title: Materials Data on GdCo9Si4 by Materials Project

Abstract

GdCo9Si4 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight equivalent Si4- atoms. All Gd–Si bond lengths are 3.17 Å. There are three inequivalent Co+1.44+ sites. In the first Co+1.44+ site, Co+1.44+ is bonded in a 3-coordinate geometry to one Co+1.44+ and four equivalent Si4- atoms. The Co–Co bond length is 2.13 Å. There are two shorter (2.29 Å) and two longer (2.91 Å) Co–Si bond lengths. In the second Co+1.44+ site, Co+1.44+ is bonded to four equivalent Si4- atoms to form a mixture of distorted corner and edge-sharing CoSi4 tetrahedra. There are a spread of Co–Si bond distances ranging from 2.28–2.43 Å. In the third Co+1.44+ site, Co+1.44+ is bonded in a square co-planar geometry to four equivalent Co+1.44+ atoms. Si4- is bonded in a 10-coordinate geometry to two equivalent Gd3+ and eight Co+1.44+ atoms.
