Nd23Ni7Cd4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are nine inequivalent Nd sites. In the first Nd site, Nd is bonded in a distorted bent 150 degrees geometry to two equivalent Ni and two Cd atoms. Both Nd–Ni bond lengths are 2.87 Å. There are one shorter (3.62 Å) and one longer (3.66 Å) Nd–Cd bond lengths. In the second Nd site, Nd is bonded in a distorted T-shaped geometry to three Ni atoms. There are two shorter (2.93 Å) and one longer (3.00 Å) Nd–Ni bond lengths. In the third Nd site, Nd is bonded in a distorted bent 150 degrees geometry to two Ni and two equivalent Cd atoms. There are one shorter (2.86 Å) and one longer (2.88 Å) Nd–Ni bond lengths. Both Nd–Cd bond lengths are 3.62 Å. In the fourth Nd site, Nd is bonded in a 3-coordinate geometry to three Ni and three Cd atoms. There are two shorter (2.88 Å) and one longer (2.89 Å) Nd–Ni bond lengths. There are two shorter (3.54 Å) and one longer (3.58 Å) Nd–Cd bond lengths. In the fifth Nd site, Nd is bonded in a 1-coordinate geometry to two equivalent Ni and one Cd atom. Both Nd–Ni bond lengths are 3.62 Å. The Nd–Cd bond length is 3.38 Å. In the sixth Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Ni atoms. All Nd–Ni bond lengths are 2.90 Å. In the seventh Nd site, Nd is bonded in a 2-coordinate geometry to four Ni and one Cd atom. There are two shorter (2.81 Å) and two longer (3.60 Å) Nd–Ni bond lengths. The Nd–Cd bond length is 3.40 Å. In the eighth Nd site, Nd is bonded in a 4-coordinate geometry to two Ni and two equivalent Cd atoms. There are one shorter (3.46 Å) and one longer (3.61 Å) Nd–Ni bond lengths. Both Nd–Cd bond lengths are 3.39 Å. In the ninth Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Ni and three equivalent Cd atoms. All Nd–Ni bond lengths are 2.86 Å. All Nd–Cd bond lengths are 3.58 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 6-coordinate geometry to nine Nd atoms. In the second Ni site, Ni is bonded in a 6-coordinate geometry to eight Nd atoms. In the third Ni site, Ni is bonded in a 6-coordinate geometry to nine Nd atoms. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to nine Nd and three equivalent Cd atoms to form face-sharing CdNd9Cd3 cuboctahedra. All Cd–Cd bond lengths are 3.16 Å. In the second Cd site, Cd is bonded to nine Nd and three Cd atoms to form a mixture of distorted corner and face-sharing CdNd9Cd3 cuboctahedra. Both Cd–Cd bond lengths are 3.18 Å.
