The crystal structure described by Tm(CoB)4 crystallizes in the tetragonal P4_2/nmc space group. Tm(1) is bonded in a 24-coordinate geometry to twelve equivalent Co(1) and twelve equivalent B(1) atoms. Co(1) is bonded in a 5-coordinate geometry to three equivalent Tm(1) and five equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Tm(1), five equivalent Co(1), and one B(1) atom. is represented by the CIF card [CIF]
