Materials Data on TbAgAs2 by Materials Project

Abstract

TbAgAs2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Tb3+ is bonded in a 8-coordinate geometry to eight As2- atoms. There are four shorter (2.96 Å) and four longer (3.11 Å) Tb–As bond lengths. Ag1+ is bonded in a 8-coordinate geometry to four equivalent Ag1+ and four equivalent As2- atoms. All Ag–Ag bond lengths are 2.82 Å. All Ag–As bond lengths are 2.80 Å. There are two inequivalent As2- sites. In the first As2- site, As2- is bonded in a 8-coordinate geometry to four equivalent Tb3+ and four equivalent As2- atoms. All As–As bond lengths are 2.82 Å. In the second As2- site, As2- is bonded in a 8-coordinate geometry to four equivalent Tb3+ and four equivalent Ag1+ atoms.
