Materials Data on K6Tl17 by Materials Project
K6Tl17 is beta Plutonium-derived structured and crystallizes in the orthorhombic Cccm space group. The structure is three-dimensional. there are five inequivalent K sites. In the first K site, K is bonded in a 10-coordinate geometry to ten Tl atoms. There are a spread of K–Tl bond distances ranging from 3.67–3.93 Å. In the second K site, K is bonded in a 8-coordinate geometry to two equivalent K and eight Tl atoms. Both K–K bond lengths are 4.05 Å. There are a spread of K–Tl bond distances ranging from 3.77–3.87 Å. In the third K site, K is bonded in a 10-coordinate geometry to twelve Tl atoms. There are a spread of K–Tl bond distances ranging from 3.92–4.21 Å. In the fourth K site, K is bonded in a 9-coordinate geometry to one K and nine Tl atoms. The K–K bond length is 4.26 Å. There are a spread of K–Tl bond distances ranging from 3.66–3.99 Å. In the fifth K site, K is bonded in a 2-coordinate geometry to four K and nine Tl atoms. There are a spread of K–Tl bond distances ranging from 3.67–4.12 Å. There are twelve inequivalent Tl sites. In the first Tl site, Tl is bonded in a 10-coordinate geometry to five K and five Tl atoms. There are a spread of Tl–Tl bond distances ranging from 3.34–3.52 Å. In the second Tl site, Tl is bonded in a 12-coordinate geometry to three K and nine Tl atoms. There are a spread of Tl–Tl bond distances ranging from 3.35–3.66 Å. In the third Tl site, Tl is bonded in a 12-coordinate geometry to three K and nine Tl atoms. There are a spread of Tl–Tl bond distances ranging from 3.23–3.50 Å. In the fourth Tl site, Tl is bonded in a 2-coordinate geometry to two K and seven Tl atoms. There are one shorter (3.48 Å) and two longer (3.52 Å) Tl–Tl bond lengths. In the fifth Tl site, Tl is bonded in a 12-coordinate geometry to four K and eight Tl atoms. There are a spread of Tl–Tl bond distances ranging from 3.18–3.41 Å. In the sixth Tl site, Tl is bonded in a 12-coordinate geometry to three K and nine Tl atoms. There are a spread of Tl–Tl bond distances ranging from 3.32–3.64 Å. In the seventh Tl site, Tl is bonded in a 2-coordinate geometry to two equivalent K and five Tl atoms. The Tl–Tl bond length is 3.47 Å. In the eighth Tl site, Tl is bonded to four K and eight Tl atoms to form distorted TlK4Tl8 cuboctahedra that share corners with two equivalent TlK2Tl10 cuboctahedra and faces with four equivalent TlK4Tl8 cuboctahedra. In the ninth Tl site, Tl is bonded to four K and eight Tl atoms to form TlK4Tl8 cuboctahedra that share corners with two equivalent TlK4Tl8 cuboctahedra and faces with four TlK2Tl10 cuboctahedra. Both Tl–Tl bond lengths are 3.36 Å. In the tenth Tl site, Tl is bonded to two K and ten Tl atoms to form a mixture of distorted face and corner-sharing TlK2Tl10 cuboctahedra. Both Tl–Tl bond lengths are 3.39 Å. In the eleventh Tl site, Tl is bonded in a 4-coordinate geometry to four K and five Tl atoms. In the twelfth Tl site, Tl is bonded in a 2-coordinate geometry to two equivalent K and eight Tl atoms.
