Materials Data on Bi2Rh by Materials Project

RhBi2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rh is bonded to six Bi atoms to form a mixture of edge and corner-sharing RhBi6 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are a spread of Rh–Bi bond distances ranging from 2.72–2.81 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 3-coordinate geometry to three equivalent Rh atoms. In the second Bi site, Bi is bonded in a 4-coordinate geometry to three equivalent Rh atoms.

Materials Data on Mn5(Bi2Rh)2 by Materials Project

Mn5Rh2Bi4 crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 10-coordinate geometry to two equivalent Mn, two equivalent Rh, and six Bi atoms. Both Mn–Mn bond lengths are 3.00 Å. Both Mn–Rh bond lengths are 2.70 Å. There are a spread of Mn–Bi bond distances ranging from 3.07–3.11 Å. In the second Mn site, Mn is bonded in a 6-coordinate geometry to three equivalent Mn, three equivalent Rh, and four Bi atoms. All Mn–Rh bond lengths are 2.65 Å. There are three shorter (2.91 Å) and one longer (3.42 Å) Mn–Bi bond lengths. Rh is bonded in a 10-coordinate geometry to six Mn and four Bi atoms. There are one shorter (2.75 Å) and three longer (2.95 Å) Rh–Bi bond lengths. There are three inequivalent Bi sites. In the first Bi site, Bi is bonded in a distorted octahedral geometry to ten Mn atoms. In the second Bi site, Bi is bonded in a 10-coordinate geometry to six equivalent Mn and four equivalent Rh atoms. In the third Bi site, Bi is bonded in a 8-coordinate geometry to six Mn and two equivalent Rh atoms.
