The material structure described by HfTl3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded to four equivalent Tl(2) and eight equivalent Tl(1) atoms to form HfTl12 cuboctahedra that share corners with four equivalent Hf(1)Tl12 cuboctahedra, edges with eight equivalent Hf(1)Tl12 cuboctahedra, edges with sixteen equivalent Tl(1)Hf4Tl8 cuboctahedra, faces with four equivalent Hf(1)Tl12 cuboctahedra, and faces with eight equivalent Tl(1)Hf4Tl8 cuboctahedra. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded to four equivalent Hf(1), four equivalent Tl(1), and four equivalent Tl(2) atoms to form TlHf4Tl8 cuboctahedra that share corners with twelve equivalent Tl(1)Hf4Tl8 cuboctahedra, edges with eight equivalent Hf(1)Tl12 cuboctahedra, edges with eight equivalent Tl(1)Hf4Tl8 cuboctahedra, faces with four equivalent Hf(1)Tl12 cuboctahedra, and faces with ten equivalent Tl(1)Hf4Tl8 cuboctahedra. In the second Tl site, Tl(2) is bonded in a distorted square co-planar geometry to four equivalent Hf(1) and eight equivalent Tl(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
