Materials Data on Tb3Ge3Ir2 by Materials Project

Abstract

Tb3Ir2Ge3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 11-coordinate geometry to four equivalent Ir and seven Ge atoms. There are a spread of Tb–Ir bond distances ranging from 3.00–3.29 Å. There are a spread of Tb–Ge bond distances ranging from 3.03–3.28 Å. In the second Tb site, Tb is bonded in a 9-coordinate geometry to four equivalent Ir and five Ge atoms. All Tb–Ir bond lengths are 3.10 Å. There are a spread of Tb–Ge bond distances ranging from 3.03–3.14 Å. Ir is bonded in a 10-coordinate geometry to six Tb and four Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.50–2.70 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Tb, three equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.79 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb and two equivalent Ir atoms.
