Materials Data on Tm(BRh)4 by Materials Project

TmRh4B4 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional. Tm is bonded in a 12-coordinate geometry to twelve equivalent Rh and twelve equivalent B atoms. There are four shorter (2.95 Å) and eight longer (3.17 Å) Tm–Rh bond lengths. There are eight shorter (3.02 Å) and four longer (3.16 Å) Tm–B bond lengths. Rh is bonded in a 5-coordinate geometry to three equivalent Tm and five equivalent B atoms. There are two shorter (2.21 Å) and three longer (2.23 Å) Rh–B bond lengths. B is bonded in a 6-coordinate geometry to three equivalent Tm, five equivalent Rh, and one B atom. The B–B bond length is 1.79 Å.
