MoGe3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Mo(1) is bonded to four equivalent Ge(2) and eight equivalent Ge(1) atoms to form MoGe12 cuboctahedra that share corners with four equivalent Mo(1)Ge12 cuboctahedra, corners with eight equivalent Ge(2)Ge8Mo4 cuboctahedra, edges with eight equivalent Mo(1)Ge12 cuboctahedra, edges with sixteen equivalent Ge(1)Ge8Mo4 cuboctahedra, faces with four equivalent Mo(1)Ge12 cuboctahedra, faces with six equivalent Ge(2)Ge8Mo4 cuboctahedra, and faces with eight equivalent Ge(1)Ge8Mo4 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Mo(1), four equivalent Ge(1), and four equivalent Ge(2) atoms to form GeGe8Mo4 cuboctahedra that share corners with twelve equivalent Ge(1)Ge8Mo4 cuboctahedra, edges with eight equivalent Mo(1)Ge12 cuboctahedra, edges with eight equivalent Ge(1)Ge8Mo4 cuboctahedra, edges with eight equivalent Ge(2)Ge8Mo4 cuboctahedra, faces with four equivalent Mo(1)Ge12 cuboctahedra, faces with four equivalent Ge(2)Ge8Mo4 cuboctahedra, and faces with ten equivalent Ge(1)Ge8Mo4 cuboctahedra. In the second Ge site, Ge(2) is bonded to four equivalent Mo(1) and eight equivalent Ge(1) atoms to form GeGe8Mo4 cuboctahedra that share corners with four equivalent Ge(2)Ge8Mo4 cuboctahedra, corners with eight equivalent Mo(1)Ge12 cuboctahedra, edges with eight equivalent Ge(2)Ge8Mo4 cuboctahedra, edges with sixteen equivalent Ge(1)Ge8Mo4 cuboctahedra, faces with four equivalent Ge(2)Ge8Mo4 cuboctahedra, faces with six equivalent Mo(1)Ge12 cuboctahedra, and faces with eight equivalent Ge(1)Ge8Mo4 cuboctahedra.
