Materials Data on ErNbO2 by Materials Project
ErNbO2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Er is bonded to six equivalent O atoms to form edge-sharing ErO6 octahedra. There are two shorter (2.29 Å) and four longer (2.31 Å) Er–O bond lengths. Nb is bonded in a square co-planar geometry to four equivalent O atoms. All Nb–O bond lengths are 2.21 Å. O is bonded to three equivalent Er and two equivalent Nb atoms to form a mixture of distorted edge and corner-sharing OEr3Nb2 trigonal bipyramids.
