Materials Data on Gd3BiO3 by Materials Project

Abstract

Gd3BiO3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Gd sites. In the first Gd site, Gd is bonded in a 4-coordinate geometry to four equivalent Bi and four O atoms. There are two shorter (3.46 Å) and two longer (3.51 Å) Gd–Bi bond lengths. There are a spread of Gd–O bond distances ranging from 2.28–2.69 Å. In the second Gd site, Gd is bonded in a distorted see-saw-like geometry to two equivalent Bi and four O atoms. Both Gd–Bi bond lengths are 3.35 Å. There are a spread of Gd–O bond distances ranging from 2.25–2.35 Å. In the third Gd site, Gd is bonded in a distorted see-saw-like geometry to two equivalent Bi and four O atoms. Both Gd–Bi bond lengths are 3.30 Å. There are a spread of Gd–O bond distances ranging from 2.26–2.49 Å. Bi is bonded in a body-centered cubic geometry to eight Gd atoms. There are three inequivalent O sites. In the first O site, O is bonded to four Gd atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra. In the second O site, O is bonded to four Gd atoms to form a mixture of edge and corner-sharing OGd4 trigonal pyramids. In the third O site, O is bonded to four Gd atoms to form a mixture of distorted edge and corner-sharing OGd4 trigonal pyramids.
