Materials Data on TbGe2Pd by Materials Project

Abstract

TbPdGe2 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 four equivalent Pd and ten Ge atoms. All Tb–Pd bond lengths are 3.27 Å. There are a spread of Tb–Ge bond distances ranging from 3.27–3.41 Å. In the second Tb site, Tb is bonded in a 12-coordinate geometry to six equivalent Pd and eight Ge atoms. There are four shorter (3.22 Å) and two longer (3.33 Å) Tb–Pd bond lengths. There are six shorter (3.03 Å) and two longer (3.09 Å) Tb–Ge bond lengths. Pd is bonded in a 10-coordinate geometry to five Tb and five Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.49–2.70 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 Pd, and one Ge atom. The Ge–Ge bond length is 2.64 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Tb, two equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.45 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Tb, two equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.47 Å.
