The material structure described by Ag2Si is Hexagonal Laves structured and crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent Ag(2) and four equivalent Ag(3) atoms. In the second Ag site, Ag(2) is bonded in a distorted q6 geometry to two equivalent Ag(1), four equivalent Ag(3), and four equivalent Si(1) atoms. In the third Ag site, Ag(3) is bonded in a distorted q6 geometry to two equivalent Ag(1), two equivalent Ag(2), two equivalent Ag(3), and four equivalent Si(1) atoms. Si(1) is bonded in a 1-coordinate geometry to two equivalent Ag(2), four equivalent Ag(3), and one Si(1) atom. is represented by the CIF file [CIF]
