The compound described by Gd(AgSi)2 crystallizes in the tetragonal I4/mmm space group. Gd(1) is bonded in a 16-coordinate geometry to eight equivalent Ag(1) and eight equivalent Si(1) atoms. Ag(1) is bonded to four equivalent Gd(1), four equivalent Ag(1), and four equivalent Si(1) atoms to form a mixture of distorted edge, face, and corner-sharing AgGd4Si4Ag4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), four equivalent Ag(1), and one Si(1) atom. is represented by the CIF card [CIF]
