Materials Data on TbGe2Ir by Materials Project

TbIrGe2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 8-coordinate geometry to six equivalent Ir and nine Ge atoms. There are four shorter (3.25 Å) and two longer (3.28 Å) Tb–Ir bond lengths. There are a spread of Tb–Ge bond distances ranging from 2.96–3.51 Å. In the second Tb site, Tb is bonded in a 8-coordinate geometry to four equivalent Ir and ten Ge atoms. All Tb–Ir bond lengths are 3.19 Å. There are a spread of Tb–Ge bond distances ranging from 3.27–3.42 Å. Ir is bonded in a 10-coordinate geometry to five Tb and five Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.48–2.64 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four Tb, three equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.74 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Tb, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.49 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to five Tb and two equivalent Ir atoms.
