The compound described by GdAgSi crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 11-coordinate geometry to six equivalent Ag(1), one Si(2), and four equivalent Si(1) atoms. Ag(1) is bonded to six equivalent Gd(1), two equivalent Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms to form a mixture of distorted face, corner, and edge-sharing AgGd6Si4Ag2 cuboctahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Gd(1) and three equivalent Ag(1) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to three equivalent Gd(1) and six equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
