Materials Data on Tb5Ir2 by Materials Project
Tb5Ir2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Tb sites. In the first Tb site, Tb is bonded in a 2-coordinate geometry to three equivalent Ir atoms. There are a spread of Tb–Ir bond distances ranging from 2.75–3.39 Å. In the second Tb site, Tb is bonded to four equivalent Ir atoms to form distorted edge-sharing TbIr4 tetrahedra. There are two shorter (2.90 Å) and two longer (2.96 Å) Tb–Ir bond lengths. In the third Tb site, Tb is bonded in a 3-coordinate geometry to three equivalent Ir atoms. There are a spread of Tb–Ir bond distances ranging from 2.86–3.07 Å. Ir is bonded in a 7-coordinate geometry to eight Tb atoms.
