The crystal structure described by TmCoSi2 crystallizes in the orthorhombic Cmcm space group. Tm(1) is bonded in a 14-coordinate geometry to four equivalent Co(1), four equivalent Si(2), and six equivalent Si(1) atoms. Co(1) is bonded in a 9-coordinate geometry to four equivalent Tm(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1), one Co(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to four equivalent Tm(1) and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
