Materials Data on TbNiAs by Materials Project
TbNiAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Tb is bonded to six equivalent Ni and six equivalent As atoms to form a mixture of edge and face-sharing TbNi6As6 cuboctahedra. All Tb–Ni bond lengths are 3.05 Å. All Tb–As bond lengths are 3.05 Å. Ni is bonded in a 3-coordinate geometry to six equivalent Tb and three equivalent As atoms. All Ni–As bond lengths are 2.34 Å. As is bonded in a 3-coordinate geometry to six equivalent Tb and three equivalent Ni atoms.
