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

Abstract

Pu(IrSi)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pu is bonded in a 8-coordinate geometry to eight Ir and eight Si atoms. There are four shorter (3.13 Å) and four longer (3.24 Å) Pu–Ir bond lengths. There are four shorter (3.14 Å) and four longer (3.18 Å) Pu–Si bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to four equivalent Pu and five Si atoms. There are one shorter (2.37 Å) and four longer (2.42 Å) Ir–Si bond lengths. In the second Ir site, Ir is bonded to four equivalent Pu and four equivalent Si atoms to form distorted IrPu4Si4 tetrahedra that share corners with twelve equivalent SiPu4Ir4 tetrahedra, edges with two equivalent SiPu4Ir4 tetrahedra, edges with four equivalent IrPu4Si4 tetrahedra, and faces with four equivalent IrPu4Si4 tetrahedra. All Ir–Si bond lengths are 2.43 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to four equivalent Pu and five Ir atoms.
