Materials Data on Tm(Ni2As)2 by Materials Project

Tm(Ni2As)2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Tm is bonded to six equivalent As atoms to form a mixture of distorted edge and corner-sharing TmAs6 octahedra. The corner-sharing octahedral tilt angles are 41°. There are two shorter (2.88 Å) and four longer (2.90 Å) Tm–As bond lengths. Ni is bonded in a 3-coordinate geometry to three equivalent As atoms. All Ni–As bond lengths are 2.39 Å. As is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Ni atoms.
