MgYb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Yb(1) atoms to form MgYb12 cuboctahedra that share corners with twelve equivalent Mg(1)Yb12 cuboctahedra, edges with twenty-four equivalent Yb(1)Yb8Mg4 cuboctahedra, faces with six equivalent Mg(1)Yb12 cuboctahedra, and faces with twelve equivalent Yb(1)Yb8Mg4 cuboctahedra. Yb(1) is bonded to four equivalent Mg(1) and eight equivalent Yb(1) atoms to form YbYb8Mg4 cuboctahedra that share corners with twelve equivalent Yb(1)Yb8Mg4 cuboctahedra, edges with eight equivalent Mg(1)Yb12 cuboctahedra, edges with sixteen equivalent Yb(1)Yb8Mg4 cuboctahedra, faces with four equivalent Mg(1)Yb12 cuboctahedra, and faces with fourteen equivalent Yb(1)Yb8Mg4 cuboctahedra.
