The material described by Hg3Ge is beta-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Hg(1) is bonded to eight equivalent Hg(1) and four equivalent Ge(1) atoms to form HgHg8Ge4 cuboctahedra that share corners with four equivalent Ge(1)Hg12 cuboctahedra, corners with fourteen equivalent Hg(1)Hg8Ge4 cuboctahedra, edges with six equivalent Ge(1)Hg12 cuboctahedra, edges with twelve equivalent Hg(1)Hg8Ge4 cuboctahedra, faces with four equivalent Ge(1)Hg12 cuboctahedra, and faces with sixteen equivalent Hg(1)Hg8Ge4 cuboctahedra. Ge(1) is bonded to twelve equivalent Hg(1) atoms to form GeHg12 cuboctahedra that share corners with six equivalent Ge(1)Hg12 cuboctahedra, corners with twelve equivalent Hg(1)Hg8Ge4 cuboctahedra, edges with eighteen equivalent Hg(1)Hg8Ge4 cuboctahedra, faces with eight equivalent Ge(1)Hg12 cuboctahedra, and faces with twelve equivalent Hg(1)Hg8Ge4 cuboctahedra. is represented by the CIF card [CIF]
