In the second Y site, Y is bonded to three equivalent Mg and nine Y atoms to form YY9Mg3 cuboctahedra that share corners with six equivalent MgY6 cuboctahedra, corners with eighteen equivalent YY9Mg3 cuboctahedra, edges with six equivalent MgY6 cuboctahedra, edges with twelve YY12 cuboctahedra, and faces with fourteen YY12 cuboctahedra. All Y–Y bond lengths are 3.54 Å.
