Materials Data on KAlTe2 by Materials Project
Abstract
KAlTe2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two 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 3.57–3.72 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 3.67–3.72 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four Te2- atoms to form corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.63–2.66 Å. In the second Al3+ site, Al3+ is bonded to four Te2- atoms to form corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.63–2.66 Å. There are five inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a distorted rectangular see-saw-like geometry to two K1+ and two Al3+ atoms. In the second Te2- site, Te2- is bonded in a 2-coordinate geometry to four K1+ and two Al3+ atoms. In the third Te2- site, Te2- is bonded in a 4-coordinate geometry to two K1+ andmore »
