Materials Data on Tm2NiAs2 by Materials Project

Tm2NiAs2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tm is bonded in a 9-coordinate geometry to three equivalent Ni and six As atoms. All Tm–Ni bond lengths are 2.99 Å. There are three shorter (2.87 Å) and three longer (2.99 Å) Tm–As bond lengths. Ni is bonded in a 3-coordinate geometry to six equivalent Tm and three equivalent As atoms. All Ni–As bond lengths are 2.35 Å. There are two inequivalent As sites. In the first As site, As is bonded to six equivalent Tm atoms to form edge-sharing AsTm6 octahedra. In the second As site, As is bonded in a 3-coordinate geometry to six equivalent Tm and three equivalent Ni atoms.
