The material structure described by Y3Ge is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to four equivalent Y(1), four equivalent Y(2), and four equivalent Ge(1) atoms to form distorted YY8Ge4 cuboctahedra that share corners with twelve equivalent Y(1)Y8Ge4 cuboctahedra, edges with eight equivalent Y(1)Y8Ge4 cuboctahedra, edges with eight equivalent Ge(1)Y12 cuboctahedra, faces with four equivalent Ge(1)Y12 cuboctahedra, and faces with ten equivalent Y(1)Y8Ge4 cuboctahedra. In the second Y site, Y(2) is bonded in a square co-planar geometry to eight equivalent Y(1) and four equivalent Ge(1) atoms. Ge(1) is bonded to four equivalent Y(2) and eight equivalent Y(1) atoms to form GeY12 cuboctahedra that share corners with four equivalent Ge(1)Y12 cuboctahedra, edges with eight equivalent Ge(1)Y12 cuboctahedra, edges with sixteen equivalent Y(1)Y8Ge4 cuboctahedra, faces with four equivalent Ge(1)Y12 cuboctahedra, and faces with eight equivalent Y(1)Y8Ge4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
