The crystal structure described by Rh3Si2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a body-centered cubic geometry to three equivalent Rh(2) and five equivalent Rh(1) atoms. is represented by the CIF file [CIF]
