The material structure described by Au3Ge is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded to eight equivalent Au(1) and four equivalent Ge(1) atoms to form distorted AuGe4Au8 cuboctahedra that share corners with four equivalent Ge(1)Au12 cuboctahedra, corners with fourteen equivalent Au(1)Ge4Au8 cuboctahedra, edges with six equivalent Ge(1)Au12 cuboctahedra, edges with twelve equivalent Au(1)Ge4Au8 cuboctahedra, faces with four equivalent Ge(1)Au12 cuboctahedra, and faces with sixteen equivalent Au(1)Ge4Au8 cuboctahedra. Ge(1) is bonded to twelve equivalent Au(1) atoms to form GeAu12 cuboctahedra that share corners with six equivalent Ge(1)Au12 cuboctahedra, corners with twelve equivalent Au(1)Ge4Au8 cuboctahedra, edges with eighteen equivalent Au(1)Ge4Au8 cuboctahedra, faces with eight equivalent Ge(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)Ge4Au8 cuboctahedra. is represented by the CIF card [CIF]
