Title: Materials Data on Sr(SnAs)2 by Materials Project

Abstract

Sr(SnAs)2 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three Sr(SnAs)2 sheets oriented in the (0, 0, 1) direction. Sr2+ is bonded to six equivalent As3- atoms to form edge-sharing SrAs6 octahedra. All Sr–As bond lengths are 3.17 Å. Sn2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent As3- atoms. All Sn–As bond lengths are 2.83 Å. As3- is bonded to three equivalent Sr2+ and three equivalent Sn2+ atoms to form a mixture of edge and corner-sharing AsSr3Sn3 octahedra. The corner-sharing octahedral tilt angles are 0°.
