Materials Data on K16Na9(Tl6Cd)3 by Materials Project
Abstract
K16Na9(CdTl6)3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a 4-coordinate geometry to six K, four Na, and six Tl atoms. There are a spread of K–K bond distances ranging from 4.06–4.45 Å. There are two shorter (4.10 Å) and two longer (4.13 Å) K–Na bond lengths. There are a spread of K–Tl bond distances ranging from 3.99–4.20 Å. In the second K site, K is bonded in a 4-coordinate geometry to five K, four equivalent Na, two equivalent Cd, and six Tl atoms. There are two shorter (4.11 Å) and three longer (4.19 Å) K–K bond lengths. All K–Na bond lengths are 4.20 Å. Both K–Cd bond lengths are 3.96 Å. There are two shorter (4.10 Å) and four longer (4.20 Å) K–Tl bond lengths. In the third K site, K is bonded in a 3-coordinate geometry to three K and four Tl atoms. There are a spread of K–Tl bond distances ranging from 3.82–4.06 Å. In the fourth K site, K is bonded in a 6-coordinate geometry to three equivalent K and six equivalent Tl atoms.
