Materials Data on Tl3Zn by Materials Project

ZnTl3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Zn is bonded in a body-centered cubic geometry to eight equivalent Tl atoms. All Zn–Tl bond lengths are 3.32 Å. There are two inequivalent Tl sites. In the first Tl site, Tl is bonded in a body-centered cubic geometry to eight equivalent Tl atoms. All Tl–Tl bond lengths are 3.32 Å. In the second Tl site, Tl is bonded in a body-centered cubic geometry to four equivalent Zn and four equivalent Tl atoms.

Materials Data on Tl3Zn by Materials Project

ZnTl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Zn is bonded to twelve equivalent Tl atoms to form ZnTl12 cuboctahedra that share corners with twelve equivalent ZnTl12 cuboctahedra, edges with twenty-four equivalent TlTl8Zn4 cuboctahedra, faces with six equivalent ZnTl12 cuboctahedra, and faces with twelve equivalent TlTl8Zn4 cuboctahedra. All Zn–Tl bond lengths are 3.39 Å. Tl is bonded to four equivalent Zn and eight equivalent Tl atoms to form TlTl8Zn4 cuboctahedra that share corners with twelve equivalent TlTl8Zn4 cuboctahedra, edges with eight equivalent ZnTl12 cuboctahedra, edges with sixteen equivalent TlTl8Zn4 cuboctahedra, faces with four equivalent ZnTl12 cuboctahedra, and faces with fourteen equivalent TlTl8Zn4 cuboctahedra. All Tl–Tl bond lengths are 3.39 Å.

Materials Data on Tl3Zn by Materials Project

ZnTl3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Zn is bonded to twelve Tl atoms to form distorted ZnTl12 cuboctahedra that share corners with four equivalent ZnTl12 cuboctahedra, corners with eight equivalent TlTl8Zn4 cuboctahedra, edges with eight equivalent ZnTl12 cuboctahedra, edges with sixteen equivalent TlTl8Zn4 cuboctahedra, faces with four equivalent ZnTl12 cuboctahedra, and faces with fourteen TlTl8Zn4 cuboctahedra. There are four shorter (3.37 Å) and eight longer (3.43 Å) Zn–Tl bond lengths. There are two inequivalent Tl sites. In the first Tl site, Tl is bonded to four equivalent Zn and eight Tl atoms to form distorted TlTl8Zn4 cuboctahedra that share corners with twelve equivalent TlTl8Zn4 cuboctahedra, edges with eight equivalent ZnTl12 cuboctahedra, edges with sixteen TlTl8Zn4 cuboctahedra, faces with four equivalent ZnTl12 cuboctahedra, and faces with fourteen TlTl8Zn4 cuboctahedra. There are four shorter (3.37 Å) and four longer (3.43 Å) Tl–Tl bond lengths.
