The compound described by Y3Rh2Si3 crystallizes in the orthorhombic Cmcm 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 9-coordinate geometry to four equivalent Rh(1), two equivalent Si(1), and three equivalent Si(2) atoms. Rh(1) is bonded in a 10-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 three equivalent Y(2), four equivalent Y(1), and two equivalent Rh(1) atoms. is represented by the CIF file [CIF]
