The crystal structure described by Ba(AlSn) crystallizes in the hexagonal P-6m2 space group. Ba(1) is bonded to six equivalent Al(1) and six equivalent Sn(1) atoms to form a mixture of edge and face-sharing BaAl6Sn6 cuboctahedra. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Ba(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a distorted trigonal planar geometry to six equivalent Ba(1) and three equivalent Al(1) atoms. is represented by the CIF card [CIF]
