Y Ge Au
YAuGe crystallizes in the trigonal R3m space group. Y(1) is bonded to three equivalent Au(1) and four equivalent Ge(1) atoms to form distorted YGe4Au3 hexagonal pyramids that share corners with three equivalent Ge(1)Y4Au3 hexagonal pyramids, corners with six equivalent Y(1)Ge4Au3 hexagonal pyramids, edges with three equivalent Ge(1)Y4Au3 hexagonal pyramids, and edges with six equivalent Y(1)Ge4Au3 hexagonal pyramids. All Y(1)-Au(1) bond lengths are 2.69 Å. There are three shorter (2.77 Å) and one longer (3.06 Å) Y(1)-Ge(1) bond length. Au(1) is bonded in a hexagonal planar geometry to three equivalent Y(1) and three equivalent Ge(1) atoms. All Au(1)-Ge(1) bond lengths are 2.69 Å. Ge(1) is bonded to four equivalent Y(1) and three equivalent Au(1) atoms to form GeY4Au3 hexagonal pyramids that share corners with three equivalent Y(1)Ge4Au3 hexagonal pyramids, corners with six equivalent Ge(1)Y4Au3 hexagonal pyramids, edges with three equivalent Y(1)Ge4Au3 hexagonal pyramids, and edges with six equivalent Ge(1)Y4Au3 hexagonal pyramids.
