The compound described by Sc5Co4Si10 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 16-coordinate geometry to four equivalent Co(1), four equivalent Si(2), and eight equivalent Si(3) atoms. In the second Sc site, Sc(2) is bonded to four equivalent Co(1), two equivalent Si(1), two equivalent Si(3), and four equivalent Si(2) atoms to form distorted face-sharing ScCo4Si8 cuboctahedra. In the third Sc site, Sc(3) is bonded in a 14-coordinate geometry to four equivalent Co(1), two equivalent Si(3), four equivalent Si(1), and four equivalent Si(2) atoms. Co(1) is bonded in a 10-coordinate geometry to one Sc(1), two equivalent Sc(2), two equivalent Sc(3), one Si(1), two equivalent Si(2), and two equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Sc(2), four equivalent Sc(3), two equivalent Co(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to one Sc(1), two equivalent Sc(2), two equivalent Sc(3), two equivalent Co(1), one Si(2), and two equivalent Si(3) atoms. In the third Si site, Si(3) is bonded in a 10-coordinate geometry to one Sc(2), one Sc(3), two equivalent Sc(1), two equivalent Co(1), two equivalent Si(2), and two equivalent Si(3) atoms. is represented by the CIF card [CIF]
