Materials Data on TbAs by Materials Project

TbAs is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tb3+ is bonded to six equivalent As3- atoms to form a mixture of edge and corner-sharing TbAs6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Tb–As bond lengths are 2.93 Å. As3- is bonded to six equivalent Tb3+ atoms to form a mixture of edge and corner-sharing AsTb6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on TbAs3 by Materials Project

TbAs3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tb3+ is bonded to twelve equivalent As1- atoms to form a mixture of distorted face and corner-sharing TbAs12 cuboctahedra. There are six shorter (3.01 Å) and six longer (3.19 Å) Tb–As bond lengths. As1- is bonded in a 6-coordinate geometry to four equivalent Tb3+ and two equivalent As1- atoms. Both As–As bond lengths are 2.67 Å.
