NaAl2Sb crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to six equivalent Al(1) and six equivalent Sb(1) atoms to form a mixture of distorted corner and face-sharing NaAl6Sb6 cuboctahedra. Al(1) is bonded in a distorted body-centered cubic geometry to three equivalent Na(1), one Al(1), and four equivalent Sb(1) atoms. Sb(1) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Al(1) atoms.
NaAl2Sb crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to six equivalent Al(1) and six equivalent Sb(1) atoms to form a mixture of distorted corner and face-sharing NaAl6Sb6 cuboctahedra. All Na(1)-Al(1) bond lengths are 3.05 Å. All Na(1)-Sb(1) bond lengths are 3.66 Å. Al(1) is bonded in a distorted body-centered cubic geometry to three equivalent Na(1), one Al(1), and four equivalent Sb(1) atoms. The Al(1)-Al(1) bond length is 2.75 Å. There is one shorter (2.95 Å) and three longer (3.25 Å) Al(1)-Sb(1) bond lengths. Sb(1) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Al(1) atoms.
