Materials Data on Dy7(TeIr)2 by Materials Project

Abstract

Dy7Ir2Te2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are four inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to three equivalent Ir and one Te atom. There are two shorter (2.86 Å) and one longer (3.11 Å) Dy–Ir bond lengths. The Dy–Te bond length is 3.18 Å. In the second Dy site, Dy is bonded in a 4-coordinate geometry to two equivalent Ir and two equivalent Te atoms. Both Dy–Ir bond lengths are 2.89 Å. Both Dy–Te bond lengths are 3.21 Å. In the third Dy site, Dy is bonded in a 3-coordinate geometry to three Te atoms. There are one shorter (3.17 Å) and two longer (3.18 Å) Dy–Te bond lengths. In the fourth Dy site, Dy is bonded in a 5-coordinate geometry to two equivalent Ir and three Te atoms. Both Dy–Ir bond lengths are 2.85 Å. There are one shorter (3.13 Å) and two longer (3.22 Å) Dy–Te bond lengths. Ir is bonded in a 7-coordinate geometry to seven Dy atoms. There are two inequivalent Te sites. In the first Te site, Te is bonded in a 8-coordinate geometry to eight Dy atoms. In the second Te site, Te is bonded in a 7-coordinate geometry to seven Dy atoms.
