The compound described by Y2RhSi2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), two equivalent Si(2), and four equivalent Si(1) atoms. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to two equivalent Rh(1), one Si(1), and five equivalent Si(2) atoms. Rh(1) is bonded in a 4-coordinate geometry to two equivalent Y(2), four equivalent Y(1), one Si(2), and three equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to one Y(2), four equivalent Y(1), three equivalent Rh(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), five equivalent Y(2), one Rh(1), and one Si(2) atom. is represented by the CIF file [CIF]
