The structure described by TbNi3Al8 crystallizes in the orthorhombic Amm2 space group. Tb(1) is bonded in a 15-coordinate geometry to two equivalent Ni(2), one Al(2), two equivalent Al(1), two equivalent Al(4), four equivalent Al(3), and four equivalent Al(5) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 7-coordinate geometry to two equivalent Ni(3), one Al(1), two equivalent Al(4), and four equivalent Al(3) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), one Al(2), two equivalent Al(3), and four equivalent Al(4) atoms. In the third Ni site, Ni(3) is bonded in a 13-coordinate geometry to two equivalent Ni(1), one Al(1), two equivalent Al(3), four equivalent Al(4), and four equivalent Al(5) atoms. There are five inequivalent Al sites. In the first Al site, Al(1) is bonded in a 1-coordinate geometry to two equivalent Tb(1), one Ni(1), one Ni(3), and four equivalent Al(5) atoms. In the second Al site, Al(2) is bonded in a 2-coordinate geometry to one Tb(1), one Ni(2), four equivalent Al(4), and four equivalent Al(5) atoms. In the third Al site, Al(3) is bonded in a 3-coordinate geometry to two equivalent Tb(1), one Ni(2), one Ni(3), two equivalent Ni(1), one Al(5), and two equivalent Al(4) atoms. In the fourth Al site, Al(4) is bonded in a 12-coordinate geometry to one Tb(1), one Ni(1), two equivalent Ni(2), two equivalent Ni(3), one Al(4), one Al(5), two equivalent Al(2), and two equivalent Al(3) atoms. In the fifth Al site, Al(5) is bonded in a 11-coordinate geometry to two equivalent Tb(1), two equivalent Ni(3), one Al(3), one Al(4), one Al(5), two equivalent Al(1), and two equivalent Al(2) atoms. is represented by the CIF card [CIF]
