Materials Data on Si2Bi2Rh3 by Materials Project
Rh3Si2Bi2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a 6-coordinate geometry to two equivalent Si and four Bi atoms. Both Rh–Si bond lengths are 2.40 Å. There are two shorter (2.83 Å) and two longer (2.85 Å) Rh–Bi bond lengths. In the second Rh site, Rh is bonded in a 2-coordinate geometry to two equivalent Si and four Bi atoms. Both Rh–Si bond lengths are 2.39 Å. There are a spread of Rh–Bi bond distances ranging from 2.88–3.03 Å. In the third Rh site, Rh is bonded in a 6-coordinate geometry to two equivalent Si and four Bi atoms. Both Rh–Si bond lengths are 2.44 Å. There are two shorter (2.88 Å) and two longer (2.91 Å) Rh–Bi bond lengths. Si is bonded in a 5-coordinate geometry to three Rh and one Bi atom. The Si–Bi bond length is 3.19 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 6-coordinate geometry to six Rh atoms. In the second Bi site, Bi is bonded in a 8-coordinate geometry to six Rh and two equivalent Si atoms.
