Title: Materials Data on Th(SiIr)2 by Materials Project

Abstract

Th(IrSi)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Th is bonded in a 8-coordinate geometry to eight Ir and eight Si atoms. There are four shorter (3.19 Å) and four longer (3.29 Å) Th–Ir bond lengths. There are four shorter (3.21 Å) and four longer (3.23 Å) Th–Si bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded to four equivalent Th and four equivalent Si atoms to form distorted IrTh4Si4 tetrahedra that share corners with twelve equivalent SiTh4Ir4 tetrahedra, edges with two equivalent SiTh4Ir4 tetrahedra, edges with four equivalent IrTh4Si4 tetrahedra, and faces with four equivalent IrTh4Si4 tetrahedra. All Ir–Si bond lengths are 2.47 Å. In the second Ir site, Ir is bonded in a 9-coordinate geometry to four equivalent Th and five Si atoms. There are one shorter (2.42 Å) and four longer (2.45 Å) Ir–Si bond lengths. There are two inequivalent Si sites. In the first Si site, Si is bonded to four equivalent Th and four equivalent Ir atoms to form distorted SiTh4Ir4 tetrahedra that share corners with twelve equivalent IrTh4Si4 tetrahedra, edges with two equivalent IrTh4Si4 tetrahedra, edges with four equivalent SiTh4Ir4 tetrahedra, and facesmore » with four equivalent SiTh4Ir4 tetrahedra.
