The crystal structure described by UEr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. U(1) is bonded to six equivalent U(1) and six equivalent Er(1) atoms to form UEr6U6 cuboctahedra that share corners with eighteen equivalent U(1)Er6U6 cuboctahedra, edges with six equivalent U(1)Er6U6 cuboctahedra, edges with twelve equivalent Er(1)Er6U6 cuboctahedra, faces with eight equivalent U(1)Er6U6 cuboctahedra, and faces with twelve equivalent Er(1)Er6U6 cuboctahedra.
