The structure described by TmEr3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Er(1) atoms to form TmEr12 cuboctahedra that share corners with six equivalent Tm(1)Er12 cuboctahedra, corners with twelve equivalent Er(1)Er8Tm4 cuboctahedra, edges with eighteen equivalent Er(1)Er8Tm4 cuboctahedra, faces with eight equivalent Tm(1)Er12 cuboctahedra, and faces with twelve equivalent Er(1)Er8Tm4 cuboctahedra. Er(1) is bonded to four equivalent Tm(1) and eight equivalent Er(1) atoms to form ErEr8Tm4 cuboctahedra that share corners with four equivalent Tm(1)Er12 cuboctahedra, corners with fourteen equivalent Er(1)Er8Tm4 cuboctahedra, edges with six equivalent Tm(1)Er12 cuboctahedra, edges with twelve equivalent Er(1)Er8Tm4 cuboctahedra, faces with four equivalent Tm(1)Er12 cuboctahedra, and faces with sixteen equivalent Er(1)Er8Tm4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
