Materials Data on TlGaSe2 by Materials Project
Abstract
TlGaSe2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.28–3.69 Å. In the second Tl1+ site, Tl1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.30–3.79 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four Se2- atoms to form corner-sharing GaSe4 tetrahedra. There are three shorter (2.45 Å) and one longer (2.46 Å) Ga–Se bond lengths. In the second Ga3+ site, Ga3+ is bonded to four Se2- atoms to form corner-sharing GaSe4 tetrahedra. There are a spread of Ga–Se bond distances ranging from 2.43–2.46 Å. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 2-coordinate geometry to four Tl1+ and two Ga3+ atoms. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to three Tl1+ and two Ga3+ atoms. In the third Se2- site, Se2- is bonded in a 2-coordinate geometry to four Tl1+ andmore »
