TbYNi2 crystallizes in the orthorhombic Pmc2_1 space group. Tb(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. Y(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1), four equivalent Y(1), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Tb(1), three equivalent Y(1), and two equivalent Ni(1) atoms.
TbYNi2 crystallizes in the orthorhombic Pmc2_1 space group. Tb(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. There are a spread of Tb(1)-Ni(1) bond distances ranging from 2.86-3.00 Å. There are two shorter (2.88 Å) and two longer (2.90 Å) Tb(1)-Ni(2) bond lengths. Y(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are a spread of Y(1)-Ni(2) bond distances ranging from 2.87-2.99 Å. There are two shorter (2.88 Å) and two longer (2.90 Å) Y(1)-Ni(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1), four equivalent Y(1), and two equivalent Ni(2) atoms. Both Ni(1)-Ni(2) bond lengths are 2.48 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Tb(1), three equivalent Y(1), and two equivalent Ni(1) atoms.
