Materials Data on GdNbO4 by Materials Project
GdNbO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.37–2.47 Å. Nb5+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.88–2.49 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Gd3+ and one Nb5+ atom.
