The compound described by NdAgSi2 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 14-coordinate geometry to four equivalent Ag(1), four equivalent Si(2), and six equivalent Si(1) atoms. Ag(1) is bonded to four equivalent Nd(1), four equivalent Ag(1), and four equivalent Si(2) atoms to form a mixture of distorted face and corner-sharing AgNd4Si4Ag4 cuboctahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1), one Si(2), and two equivalent Si(1) atoms. In the second Si site, Si(2) 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]
