Al23Ni6Y4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 11-coordinate geometry to two equivalent Ni and thirteen Al atoms. Both Y–Ni bond lengths are 3.26 Å. There are a spread of Y–Al bond distances ranging from 3.04–3.38 Å. In the second Y site, Y is bonded in a 11-coordinate geometry to two equivalent Ni and thirteen Al atoms. Both Y–Ni bond lengths are 3.23 Å. There are a spread of Y–Al bond distances ranging from 3.06–3.32 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 7-coordinate geometry to two equivalent Y and seven Al atoms. There are a spread of Ni–Al bond distances ranging from 2.34–2.51 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to nine Al atoms. There are a spread of Ni–Al bond distances ranging from 2.40–2.72 Å. In the third Ni site, Ni is bonded in a 8-coordinate geometry to two equivalent Y and eight Al atoms. There are a spread of Ni–Al bond distances ranging from 2.39–2.57 Å. There are twelve inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to four equivalent Y and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.88–3.14 Å. In the second Al site, Al is bonded in a distorted bent 150 degrees geometry to two equivalent Y, two Ni, and five Al atoms. There are a spread of Al–Al bond distances ranging from 2.70–2.90 Å. In the third Al site, Al is bonded in a 12-coordinate geometry to four Y and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.86–3.13 Å. In the fourth Al site, Al is bonded in a distorted trigonal non-coplanar geometry to one Y, three Ni, and one Al atom. The Al–Al bond length is 2.68 Å. In the fifth Al site, Al is bonded in a distorted bent 150 degrees geometry to three Y, two Ni, and three Al atoms. Both Al–Al bond lengths are 2.74 Å. In the sixth Al site, Al is bonded in a 3-coordinate geometry to three equivalent Y, three equivalent Ni, and one Al atom. In the seventh Al site, Al is bonded in a 3-coordinate geometry to two equivalent Y, three Ni, and one Al atom. The Al–Al bond length is 2.81 Å. In the eighth Al site, Al is bonded in a 3-coordinate geometry to one Y, three equivalent Ni, and six Al atoms. There are two shorter (2.61 Å) and one longer (2.74 Å) Al–Al bond lengths. In the ninth Al site, Al is bonded to two Y, two equivalent Ni, and eight Al atoms to form distorted face-sharing AlY2Al8Ni2 cuboctahedra. The Al–Al bond length is 2.76 Å. In the tenth Al site, Al is bonded in a 2-coordinate geometry to three Y, two equivalent Ni, and one Al atom. In the eleventh Al site, Al is bonded in a distorted single-bond geometry to three Y, one Ni, and four Al atoms. In the twelfth Al site, Al is bonded in a distorted trigonal planar geometry to three Ni and two Al atoms.
