Materials Data on HoSc(BRh)8 by Materials Project

Abstract

HoSc(RhB)8 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to twelve Rh and twelve B atoms. There are four shorter (2.96 Å) and eight longer (3.18 Å) Ho–Rh bond lengths. There are eight shorter (3.02 Å) and four longer (3.14 Å) Ho–B bond lengths. Sc is bonded in a 12-coordinate geometry to twelve Rh and twelve B atoms. There are four shorter (2.92 Å) and eight longer (3.16 Å) Sc–Rh bond lengths. There are eight shorter (3.03 Å) and four longer (3.14 Å) Sc–B bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to two equivalent Ho, one Sc, and five B atoms. There are four shorter (2.21 Å) and one longer (2.26 Å) Rh–B bond lengths. In the second Rh site, Rh is bonded in a 5-coordinate geometry to one Ho, two equivalent Sc, and five B atoms. There are three shorter (2.21 Å) and two longer (2.22 Å) Rh–B bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a 6-coordinate geometry to two equivalent Ho, one Sc, five Rh, and one B atom. The B–B bond length is 1.80 Å. In the second B site, B is bonded in a 6-coordinate geometry to one Ho, two equivalent Sc, five Rh, and one B atom. The B–B bond length is 1.81 Å.
