Materials Data on TbGe2Pt by Materials Project
TbPtGe2 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 12-coordinate geometry to six equivalent Pt and eight Ge atoms. There are four shorter (3.22 Å) and two longer (3.30 Å) Tb–Pt bond lengths. There are a spread of Tb–Ge bond distances ranging from 3.02–3.07 Å. In the second Tb site, Tb is bonded in a 12-coordinate geometry to four equivalent Pt and ten Ge atoms. All Tb–Pt bond lengths are 3.28 Å. There are a spread of Tb–Ge bond distances ranging from 3.26–3.44 Å. Pt is bonded in a 10-coordinate geometry to five Tb and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.50–2.66 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 Pt, and one Ge atom. The Ge–Ge bond length is 2.63 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Tb, two equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.44 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Tb, two equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.43 Å.
