Materials Data on Tb3(AlNi3)2 by Materials Project
Tb3Ni6Al2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Tb is bonded in a 12-coordinate geometry to eight equivalent Ni and four equivalent Al atoms. There are four shorter (2.80 Å) and four longer (3.00 Å) Tb–Ni bond lengths. All Tb–Al bond lengths are 3.19 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Tb, four equivalent Ni, and two equivalent Al atoms. All Ni–Ni bond lengths are 2.58 Å. Both Ni–Al bond lengths are 2.47 Å. Al is bonded to six equivalent Tb and six equivalent Ni atoms to form a mixture of distorted corner and face-sharing AlTb6Ni6 cuboctahedra.
