Materials Data on LaNbO2 by Materials Project
LaNbO2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. La2+ is bonded to six equivalent O2- atoms to form edge-sharing LaO6 octahedra. There are two shorter (2.49 Å) and four longer (2.50 Å) La–O bond lengths. Nb2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There are two shorter (2.18 Å) and two longer (2.19 Å) Nb–O bond lengths. O2- is bonded to three equivalent La2+ and two equivalent Nb2+ atoms to form a mixture of distorted corner and edge-sharing OLa3Nb2 trigonal bipyramids.
