BeGd2Ni is Heusler structured and crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to one Gd(2) and four equivalent Gd(1) atoms. The Be(1)-Gd(2) bond length is 1.42 Å. There are three shorter (2.83 Å) and one longer (3.47 Å) Be(1)-Gd(1) bond length. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 8-coordinate geometry to four equivalent Be(1) and four equivalent Ni(1) atoms. There are three shorter (2.83 Å) and one longer (3.47 Å) Gd(1)-Ni(1) bond length. In the second Gd site, Gd(2) is bonded in a single-bond geometry to one Be(1) and four equivalent Ni(1) atoms. There are three shorter (2.83 Å) and one longer (3.47 Å) Gd(2)-Ni(1) bond length. Ni(1) is bonded in a 8-coordinate geometry to four equivalent Gd(1) and four equivalent Gd(2) atoms.
