The compound described by Ag2Hg crystallizes in the trigonal P-3m1 space group. Ag(1) is bonded to nine equivalent Ag(1) and three equivalent Hg(1) atoms to form AgAg9Hg3 cuboctahedra that share corners with three equivalent Hg(1)Ag6Hg6 cuboctahedra, corners with nine equivalent Ag(1)Ag9Hg3 cuboctahedra, edges with nine equivalent Hg(1)Ag6Hg6 cuboctahedra, edges with fifteen equivalent Ag(1)Ag9Hg3 cuboctahedra, faces with six equivalent Hg(1)Ag6Hg6 cuboctahedra, and faces with twelve equivalent Ag(1)Ag9Hg3 cuboctahedra. Hg(1) is bonded to six equivalent Ag(1) and six equivalent Hg(1) atoms to form HgAg6Hg6 cuboctahedra that share corners with six equivalent Ag(1)Ag9Hg3 cuboctahedra, corners with six equivalent Hg(1)Ag6Hg6 cuboctahedra, edges with six equivalent Hg(1)Ag6Hg6 cuboctahedra, edges with eighteen equivalent Ag(1)Ag9Hg3 cuboctahedra, faces with six equivalent Hg(1)Ag6Hg6 cuboctahedra, and faces with twelve equivalent Ag(1)Ag9Hg3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
