Abstract
LaAgAs2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight As2- atoms. There are a spread of La–As bond distances ranging from 3.12–3.33 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight As2- atoms. There are a spread of La–As bond distances ranging from 3.09–3.30 Å. There are six inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four Ag1+ and four As2- atoms. There are a spread of Ag–Ag bond distances ranging from 2.93–2.97 Å. There are two shorter (2.79 Å) and two longer (2.80 Å) Ag–As bond lengths. In the second Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four Ag1+ and four As2- atoms. There are a spread of Ag–Ag bond distances ranging from 2.93–2.97 Å. There are two shorter (2.79 Å) and two longer (2.80 Å) Ag–As bond lengths. In the third Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four Ag1+ and four As2- atoms. There are one shorter (2.93 Å) and one longer (2.97 Å)more »
