The material structure described by NdAlSn is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Nd(1) is bonded to six equivalent Al(1) and six equivalent Sn(1) atoms to form a mixture of edge and face-sharing NdAl6Sn6 cuboctahedra. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Nd(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Al(1) atoms. is represented by the CIF file [CIF]
