The crystal structure described by NdAsO2 crystallizes in the tetragonal I4_1/amd space group. Nd(1) is bonded to six equivalent O(1) atoms to form edge-sharing NdO6 octahedra. As(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Nd(1) and two equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing ONd3As2 trigonal bipyramids. is represented by the CIF file [CIF]
