Materials Data on Tm2MgNi2 by Materials Project
MgTm2Ni2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded in a distorted square co-planar geometry to four equivalent Ni atoms. All Mg–Ni bond lengths are 2.89 Å. Tm is bonded in a 6-coordinate geometry to six equivalent Ni atoms. There are two shorter (2.81 Å) and four longer (2.85 Å) Tm–Ni bond lengths. Ni is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Tm, and one Ni atom. The Ni–Ni bond length is 2.44 Å.
