Materials Data on Gd2BiO2 by Materials Project
Gd2BiO2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd is bonded in a 4-coordinate geometry to four equivalent Bi and four equivalent O atoms. All Gd–Bi bond lengths are 3.61 Å. All Gd–O bond lengths are 2.28 Å. Bi is bonded in a body-centered cubic geometry to eight equivalent Gd atoms. O is bonded to four equivalent Gd atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra.
