Materials Data on Gd3Co29(Si2B5)2 by Materials Project
Abstract
CoGd3Co28(B5Si2)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional and consists of two cobalt molecules and one Gd3Co28(B5Si2)2 framework. In the Gd3Co28(B5Si2)2 framework, there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded in a 4-coordinate geometry to four equivalent Si4- atoms. All Gd–Si bond lengths are 3.20 Å. In the second Gd3+ site, Gd3+ is bonded in a 8-coordinate geometry to four equivalent Si4- atoms. All Gd–Si bond lengths are 3.25 Å. There are six inequivalent Co+1.28+ sites. In the first Co+1.28+ site, Co+1.28+ is bonded in a square co-planar geometry to four B3- atoms. There are a spread of Co–B bond distances ranging from 2.06–2.10 Å. In the second Co+1.28+ site, Co+1.28+ is bonded in a distorted single-bond geometry to one B3- and three equivalent Si4- atoms. The Co–B bond length is 1.91 Å. There are one shorter (2.38 Å) and two longer (2.42 Å) Co–Si bond lengths. In the third Co+1.28+ site, Co+1.28+ is bonded in a distorted rectangular see-saw-like geometry to three B3- and one Si4- atom. There are a spread of Co–B bond distances ranging from 2.04–2.13 Å. The Co–Si bond length is 2.33 Å. In the fourthmore »
