The structure described by TmCoB4 crystallizes in the orthorhombic Pbam space group. Tm(1) is bonded in a 14-coordinate geometry to two equivalent B(1), four equivalent B(2), four equivalent B(3), and four equivalent B(4) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent B(2), two equivalent B(3), two equivalent B(4), and four equivalent B(1) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Tm(1), four equivalent Co(1), one B(1), one B(2), and one B(3) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Tm(1), two equivalent Co(1), one B(1), one B(2), and one B(4) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to four equivalent Tm(1), two equivalent Co(1), one B(1), and two equivalent B(4) atoms. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to four equivalent Tm(1), two equivalent Co(1), one B(2), and two equivalent B(3) atoms. is represented by the CIF file [CIF]
