Materials Data on Lu5Ir2 by Materials Project

Abstract

Lu5Ir2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Lu sites. In the first Lu site, Lu is bonded to four equivalent Ir atoms to form distorted edge-sharing LuIr4 tetrahedra. There are two shorter (2.82 Å) and two longer (2.88 Å) Lu–Ir bond lengths. In the second Lu site, Lu is bonded in a 3-coordinate geometry to three equivalent Ir atoms. There are a spread of Lu–Ir bond distances ranging from 2.81–2.96 Å. In the third Lu site, Lu is bonded in a 3-coordinate geometry to three equivalent Ir atoms. There are a spread of Lu–Ir bond distances ranging from 2.72–3.23 Å. Ir is bonded in a 8-coordinate geometry to eight Lu atoms.
