Materials Data on La2(SiIr)3 by Materials Project
La2(IrSi)3 crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one La2(IrSi)3 ribbon oriented in the (0, 0, 1) direction. La is bonded in a linear geometry to one Ir and one Si atom. The La–Ir bond length is 2.22 Å. The La–Si bond length is 2.96 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a linear geometry to one La and one Si atom. The Ir–Si bond length is 2.30 Å. In the second Ir site, Ir is bonded in a linear geometry to two equivalent Si atoms. Both Ir–Si bond lengths are 2.27 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a linear geometry to one La and one Ir atom. In the second Si site, Si is bonded in a linear geometry to two equivalent Ir atoms.
