AlNd crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. In the second Nd site, Nd(2) is bonded in a 6-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a 10-coordinate geometry to four equivalent Nd(1), four equivalent Nd(2), and two equivalent Al(1) atoms. In the second Al site, Al(1) is bonded to four equivalent Nd(1), four equivalent Nd(2), two equivalent Al(1), and two equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlNd8Al4 cuboctahedra.
AlNd crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are two shorter (3.44 Å) and two longer (3.48 Å) Nd(1)-Al(1) bond lengths. There are a spread of Nd(1)-Al(2) bond distances ranging from 3.15-3.31 Å. In the second Nd site, Nd(2) is bonded in a 6-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are two shorter (3.35 Å) and two longer (3.57 Å) Nd(2)-Al(1) bond lengths. There are a spread of Nd(2)-Al(2) bond distances ranging from 3.16-3.36 Å. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a 10-coordinate geometry to four equivalent Nd(1), four equivalent Nd(2), and two equivalent Al(1) atoms. Both Al(2)-Al(1) bond lengths are 2.74 Å. In the second Al site, Al(1) is bonded to four equivalent Nd(1), four equivalent Nd(2), two equivalent Al(1), and two equivalent Al(2) atoms to form a mixture of edge, corner, and face-sharing AlNd8Al4 cuboctahedra. Both Al(1)-Al(1) bond lengths are 2.88 Å.
