The material described by GdCr2Si2 crystallizes in the triclinic P1 space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent Si(1) and four equivalent Si(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent Si(1) and two equivalent Si(2) atoms to form a mixture of distorted corner and edge-sharing CrSi4 tetrahedra. In the second Cr site, Cr(2) is bonded to two equivalent Si(1) and two equivalent Si(2) atoms to form a mixture of distorted corner and edge-sharing CrSi4 tetrahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Cr(1), two equivalent Cr(2), and one Si(2) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Cr(1), two equivalent Cr(2), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
