Materials Data on Tb2ZnNi2 by Materials Project

Tb2Ni2Zn crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Tb is bonded in a 10-coordinate geometry to six equivalent Ni and four equivalent Zn atoms. There are two shorter (2.83 Å) and four longer (2.96 Å) Tb–Ni bond lengths. There are two shorter (3.15 Å) and two longer (3.22 Å) Tb–Zn bond lengths. Ni is bonded in a 9-coordinate geometry to six equivalent Tb, one Ni, and two equivalent Zn atoms. The Ni–Ni bond length is 2.48 Å. Both Ni–Zn bond lengths are 2.57 Å. Zn is bonded to eight equivalent Tb and four equivalent Ni atoms to form a mixture of distorted edge and face-sharing ZnTb8Ni4 cuboctahedra.

Materials Data on TbZnNi by Materials Project

TbNiZn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Tb is bonded in a 11-coordinate geometry to five Ni and six equivalent Zn atoms. There are four shorter (2.85 Å) and one longer (2.88 Å) Tb–Ni bond lengths. There are two shorter (3.10 Å) and four longer (3.14 Å) Tb–Zn bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three equivalent Tb and six equivalent Zn atoms. All Ni–Zn bond lengths are 2.54 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to six equivalent Tb and three equivalent Zn atoms. All Ni–Zn bond lengths are 2.72 Å. Zn is bonded in a 12-coordinate geometry to six equivalent Tb, four Ni, and two equivalent Zn atoms. Both Zn–Zn bond lengths are 2.95 Å.
