Materials Data on ErTl3 by Materials Project

Abstract

ErTl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded to twelve equivalent Tl atoms to form ErTl12 cuboctahedra that share corners with twelve equivalent ErTl12 cuboctahedra, edges with twenty-four equivalent TlEr4Tl8 cuboctahedra, faces with six equivalent ErTl12 cuboctahedra, and faces with twelve equivalent TlEr4Tl8 cuboctahedra. All Er–Tl bond lengths are 3.37 Å. Tl is bonded to four equivalent Er and eight equivalent Tl atoms to form TlEr4Tl8 cuboctahedra that share corners with twelve equivalent TlEr4Tl8 cuboctahedra, edges with eight equivalent ErTl12 cuboctahedra, edges with sixteen equivalent TlEr4Tl8 cuboctahedra, faces with four equivalent ErTl12 cuboctahedra, and faces with fourteen equivalent TlEr4Tl8 cuboctahedra. All Tl–Tl bond lengths are 3.37 Å.
