The material described by Th4Co10Si crystallizes in the tetragonal I4_1/amd space group. Th(1) is bonded in a 4-coordinate geometry to two equivalent Co(1) and four equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to four equivalent Th(1), eight equivalent Co(2), and two equivalent Si(1) atoms. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to two equivalent Th(1), two equivalent Co(1), and one Si(1) atom. Si(1) is bonded in a 12-coordinate geometry to four equivalent Co(1) and eight equivalent Co(2) atoms. is represented by the CIF card [CIF]
