The structure described by Y3(RhSi)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to four equivalent Rh(1) and two 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(2), and three equivalent Si(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Y(2), four equivalent Y(1), one Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to three equivalent Y(2), four equivalent Y(1), and two equivalent Rh(1) atoms. In the second Si site, Si(2) is bonded in a 4-coordinate geometry to two equivalent Y(2) and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
