Materials Data on Sr2(AsIr)3 by Materials Project

Abstract

Sr2(IrAs)3 crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one Sr2(IrAs)3 ribbon oriented in the (0, 0, 1) direction. Sr is bonded in a linear geometry to one Ir and one As atom. The Sr–Ir bond length is 2.92 Å. The Sr–As bond length is 2.91 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a linear geometry to one Sr and one As atom. The Ir–As bond length is 2.23 Å. In the second Ir site, Ir is bonded in a linear geometry to two equivalent As atoms. Both Ir–As bond lengths are 2.25 Å. There are two inequivalent As sites. In the first As site, As is bonded in a linear geometry to one Sr and one Ir atom. In the second As site, As is bonded in a linear geometry to two equivalent Ir atoms.
