NdCuAl crystallizes in the hexagonal P-62m space group. Nd(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Al(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1) and six equivalent Al(1) atoms. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Al(1) atoms. Al(1) is bonded in a 12-coordinate geometry to six equivalent Nd(1), two equivalent Cu(1), two equivalent Cu(2), and two equivalent Al(1) atoms.
NdCuAl crystallizes in the hexagonal P-62m space group. Nd(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Al(1) atoms. The Nd(1)-Cu(2) bond length is 3.02 Å. All Nd(1)-Cu(1) bond lengths are 2.97 Å. There are two shorter (3.28 Å) and four longer (3.32 Å) Nd(1)-Al(1) bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1) and six equivalent Al(1) atoms. All Cu(2)-Al(1) bond lengths are 2.61 Å. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Al(1) atoms. All Cu(1)-Al(1) bond lengths are 2.88 Å. Al(1) is bonded in a 12-coordinate geometry to six equivalent Nd(1), two equivalent Cu(1), two equivalent Cu(2), and two equivalent Al(1) atoms. Both Al(1)-Al(1) bond lengths are 2.82 Å.
