SmNbO2 crystallizes in the tetragonal I4_1/amd space group. Sm(1) is bonded to six equivalent O(1) atoms to form edge-sharing SmO6 octahedra. Nb(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Sm(1) and two equivalent Nb(1) atoms to form a mixture of distorted corner and edge-sharing OSm3Nb2 trigonal bipyramids.
SmNbO2 crystallizes in the tetragonal I4_1/amd space group. Sm(1) is bonded to six equivalent O(1) atoms to form edge-sharing SmO6 octahedra. There are two shorter (2.38 Å) and four longer (2.43 Å) Sm(1)-O(1) bond lengths. Nb(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Nb(1)-O(1) bond lengths are 2.19 Å. O(1) is bonded to three equivalent Sm(1) and two equivalent Nb(1) atoms to form a mixture of distorted corner and edge-sharing OSm3Nb2 trigonal bipyramids.
