The structure described by Gd2CoSi2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 10-coordinate geometry to four equivalent Co(1), two equivalent Si(2), and five equivalent Si(1) atoms. In the second Gd site, Gd(2) is bonded in a 6-coordinate geometry to two equivalent Co(1), one Si(1), and five equivalent Si(2) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent Gd(2), four equivalent Gd(1), one Si(2), and three equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to one Gd(2), five equivalent Gd(1), three equivalent Co(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Gd(1), five equivalent Gd(2), one Co(1), and one Si(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
