The material structure described by Tb3WB7 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 11-coordinate geometry to two equivalent B(2), two equivalent B(4), three equivalent B(1), and four equivalent B(3) atoms. In the second Tb site, Tb(2) is bonded in a 10-coordinate geometry to four equivalent B(2) and six equivalent B(1) atoms. W(1) is bonded in a 10-coordinate geometry to two equivalent B(4), four equivalent B(2), and four equivalent B(3) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), one B(2), and two equivalent B(1) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), two equivalent W(1), one B(1), one B(2), and one B(3) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to four equivalent Tb(1), two equivalent W(1), one B(2), one B(3), and one B(4) atom. In the fourth B site, B(4) is bonded in a 8-coordinate geometry to four equivalent Tb(1), two equivalent W(1), and two equivalent B(3) atoms. is represented by the CIF file [CIF]
