The compound described by GdSi crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 7-coordinate geometry to seven Si(1,1) atoms. In the second Gd site, Gd(1) is bonded in a 7-coordinate geometry to seven Si(1,1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to seven Gd(1,1) and two equivalent Si(1) atoms. In the second Si site, Si(1) is bonded in a 9-coordinate geometry to seven Gd(1,1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
