The structure described by Ag3N is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Ag(1), four equivalent Ag(2), and four equivalent N(1) atoms to form distorted AgAg8N4 cuboctahedra that share corners with twelve equivalent Ag(1)Ag8N4 cuboctahedra, edges with eight equivalent Ag(1)Ag8N4 cuboctahedra, edges with eight equivalent N(1)Ag12 cuboctahedra, faces with four equivalent N(1)Ag12 cuboctahedra, and faces with ten equivalent Ag(1)Ag8N4 cuboctahedra. In the second Ag site, Ag(2) is bonded in a distorted square co-planar geometry to eight equivalent Ag(1) and four equivalent N(1) atoms. N(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form NAg12 cuboctahedra that share corners with four equivalent N(1)Ag12 cuboctahedra, edges with eight equivalent N(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Ag8N4 cuboctahedra, faces with four equivalent N(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(1)Ag8N4 cuboctahedra. is represented by the CIF card [CIF]
