The crystal structure described by Tm3WB7 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(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 Tm site, Tm(2) is bonded in a 10-coordinate geometry to one B(4), 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 Tm(1), three equivalent Tm(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 Tm(1), two equivalent Tm(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 Tm(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 9-coordinate geometry to one Tm(2), four equivalent Tm(1), two equivalent W(1), and two equivalent B(3) atoms. is represented by the CIF file [CIF]
