Materials Data on TbNiGe3 by Materials Project
TbNiGe3 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 4-coordinate geometry to four equivalent Ni and ten Ge atoms. All Tb–Ni bond lengths are 3.16 Å. There are a spread of Tb–Ge bond distances ranging from 3.08–3.21 Å. In the second Tb site, Tb is bonded in a 4-coordinate geometry to four equivalent Ni and ten Ge atoms. All Tb–Ni bond lengths are 3.16 Å. There are a spread of Tb–Ge bond distances ranging from 3.08–3.21 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to four equivalent Tb and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.29–2.36 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to four equivalent Tb and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.29–2.36 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Tb, two equivalent Ni, and five Ge atoms. There are one shorter (2.48 Å) and four longer (2.90 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Tb, two equivalent Ni, and five Ge atoms. All Ge–Ge bond lengths are 2.90 Å. In the third Ge site, Ge is bonded in a 1-coordinate geometry to six Tb, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.50 Å. In the fourth Ge site, Ge is bonded in a 1-coordinate geometry to six Tb, one Ni, and two equivalent Ge atoms. In the fifth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Tb, two equivalent Ni, and five Ge atoms. The Ge–Ge bond length is 2.49 Å. In the sixth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Tb, two equivalent Ni, and five Ge atoms.
