The structure described by TbNi crystallizes in the orthorhombic Pnma space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1), two equivalent Ni(3), and three equivalent Ni(2) atoms. In the second Tb site, Tb(2) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(3) atoms. In the third Tb site, Tb(3) is bonded in a 7-coordinate geometry to one Ni(3), two equivalent Ni(1), and four equivalent Ni(2) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to two equivalent Tb(1), two equivalent Tb(3), three equivalent Tb(2), and two equivalent Ni(3) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to three equivalent Tb(1), four equivalent Tb(3), and two equivalent Ni(2) atoms. In the third Ni site, Ni(3) is bonded in a 9-coordinate geometry to one Tb(3), two equivalent Tb(1), four equivalent Tb(2), and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
