Materials Data on SmNbO2 by Materials Project
SmNbO2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Sm2+ is bonded to six equivalent O2- atoms to form edge-sharing SmO6 octahedra. There are a spread of Sm–O bond distances ranging from 2.38–2.43 Å. Nb2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Nb–O bond lengths are 2.19 Å. O2- is bonded to three equivalent Sm2+ and two equivalent Nb2+ atoms to form a mixture of distorted edge and corner-sharing OSm3Nb2 trigonal bipyramids.
