The structure described by TbFe2Al10 crystallizes in the orthorhombic Cmcm space group. Tb(1) is bonded in a 20-coordinate geometry to four equivalent Fe(1), two equivalent Al(2), two equivalent Al(4), four equivalent Al(1), four equivalent Al(3), and four equivalent Al(5) atoms. Fe(1) is bonded in a 10-coordinate geometry to two equivalent Tb(1), two equivalent Al(1), two equivalent Al(2), two equivalent Al(3), two equivalent Al(4), and two equivalent Al(5) atoms. There are five inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to two equivalent Tb(1), two equivalent Fe(1), two equivalent Al(2), two equivalent Al(3), two equivalent Al(4), and two equivalent Al(5) atoms. In the second Al site, Al(2) is bonded in a 12-coordinate geometry to one Tb(1), two equivalent Fe(1), one Al(2), two equivalent Al(1), two equivalent Al(3), two equivalent Al(4), and two equivalent Al(5) atoms. In the third Al site, Al(3) is bonded in a 12-coordinate geometry to two equivalent Tb(1), two equivalent Fe(1), one Al(3), one Al(4), two equivalent Al(1), two equivalent Al(2), and two equivalent Al(5) atoms.
