Title: Materials Data on AgAs(SeF2)3 by Materials Project

Abstract

AgAs(SeF2)3 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two AgAs(SeF2)3 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted octahedral geometry to six Se atoms. There are four shorter (2.98 Å) and two longer (3.04 Å) Ag–Se bond lengths. In the second Ag1+ site, Ag1+ is bonded in a 10-coordinate geometry to two equivalent Se and eight F1- atoms. Both Ag–Se bond lengths are 2.74 Å. There are four shorter (2.74 Å) and four longer (3.15 Å) Ag–F bond lengths. As5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.76–1.80 Å. There are two inequivalent Se sites. In the first Se site, Se is bonded in a distorted rectangular see-saw-like geometry to two Ag1+ and two equivalent Se atoms. Both Se–Se bond lengths are 2.40 Å. In the second Se site, Se is bonded in a distorted rectangular see-saw-like geometry to one Ag1+, two Se, and one F1- atom. The Se–Se bond length is 2.36 Å. The Se–F bond length is 3.15 Å. There aremore » three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one Ag1+, one As5+, and one Se atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Ag1+ and one As5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As5+ atom.« less
