The material structure described by Tb6FeBi2 crystallizes in the monoclinic Pm space group. There are six inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1), one Bi(1), and one Bi(2) atom. In the second Tb site, Tb(2) is bonded in a 4-coordinate geometry to two equivalent Fe(1), one Bi(1), and one Bi(2) atom. In the third Tb site, Tb(3) is bonded in a 4-coordinate geometry to two equivalent Fe(1), one Bi(1), and one Bi(2) atom. In the fourth Tb site, Tb(4) is bonded in a 5-coordinate geometry to one Fe(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. In the fifth Tb site, Tb(5) is bonded in a 5-coordinate geometry to one Fe(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. In the sixth Tb site, Tb(6) is bonded in a 5-coordinate geometry to one Fe(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. Fe(1) is bonded in a 9-coordinate geometry to one Tb(4), one Tb(5), one Tb(6), two equivalent Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 9-coordinate geometry to one Tb(1), one Tb(2), one Tb(3), two equivalent Tb(4), two equivalent Tb(5), and two equivalent Tb(6) atoms. In the second Bi site, Bi(2) is bonded in a 9-coordinate geometry to one Tb(1), one Tb(2), one Tb(3), two equivalent Tb(4), two equivalent Tb(5), and two equivalent Tb(6) atoms. is represented by the CIF file [CIF]
