Materials Data on K2Te2As by Materials Project
K2AsTe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.64–3.85 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.64–3.78 Å. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.48–3.74 Å. In the fourth K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.62–3.92 Å. There are two inequivalent As2+ sites. In the first As2+ site, As2+ is bonded in a water-like geometry to two equivalent Te2- atoms. Both As–Te bond lengths are 2.64 Å. In the second As2+ site, As2+ is bonded in a water-like geometry to two equivalent Te2- atoms. Both As–Te bond lengths are 2.63 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 7-coordinate geometry to six K1+ and one As2+ atom. In the second Te2- site, Te2- is bonded in a 7-coordinate geometry to six K1+ and one As2+ atom.
