The structure described by YRh3Si2 crystallizes in the orthorhombic Imma space group. Y(1) is bonded in a 20-coordinate geometry to two equivalent Y(1), four equivalent Rh(2), eight equivalent Rh(1), and six equivalent Si(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 6-coordinate geometry to four equivalent Y(1) and four equivalent Si(1) atoms. In the second Rh site, Rh(1) is bonded in a 6-coordinate geometry to four equivalent Y(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to three equivalent Y(1), two equivalent Rh(2), and four equivalent Rh(1) atoms. is represented by the CIF card [CIF]
