CuNdO2 crystallizes in the trigonal R-3m space group. Nd(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing NdO6 octahedra. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Nd(1) and one Cu(1) atom to form a mixture of edge and corner-sharing ONd3Cu tetrahedra.
CuNdO2 crystallizes in the trigonal R-3m space group. Nd(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing NdO6 octahedra. All Nd(1)-O(1) bond lengths are 2.40 Å. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Cu(1)-O(1) bond lengths are 1.80 Å. O(1) is bonded to three equivalent Nd(1) and one Cu(1) atom to form a mixture of edge and corner-sharing ONd3Cu tetrahedra.
