Materials Data on B3Rh7 by Materials Project
Rh7B3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a 3-coordinate geometry to three equivalent B atoms. There are one shorter (2.09 Å) and two longer (2.22 Å) Rh–B bond lengths. In the second Rh site, Rh is bonded in a 3-coordinate geometry to three equivalent B atoms. All Rh–B bond lengths are 2.23 Å. In the third Rh site, Rh is bonded in a distorted water-like geometry to two equivalent B atoms. Both Rh–B bond lengths are 2.14 Å. B is bonded in a 6-coordinate geometry to six Rh atoms.
