Materials Data on NaNdO2 by Materials Project
NaNdO2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Na1+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All Na–O bond lengths are 2.41 Å. Nd3+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing NdO6 octahedra. The corner-sharing octahedral tilt angles are 17°. There are four shorter (2.41 Å) and two longer (2.42 Å) Nd–O bond lengths. O2- is bonded to two equivalent Na1+ and three equivalent Nd3+ atoms to form a mixture of distorted edge and corner-sharing ONa2Nd3 square pyramids.
