The material described by Nd(AgSi)2 crystallizes in the tetragonal I4/mmm space group. Nd(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 Nd(1), four equivalent Ag(1), and four equivalent Si(1) atoms to form a mixture of distorted face, corner, and edge-sharing AgNd4Si4Ag4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), four equivalent Ag(1), and one Si(1) atom. is represented by the CIF file [CIF]
