The material structure described by Er2Rh3Si crystallizes in the trigonal R-3m space group. Er(1) is bonded in a 3-coordinate geometry to nine equivalent Rh(1) atoms. Rh(1) is bonded in a 12-coordinate geometry to six equivalent Er(1), four equivalent Rh(1), and two equivalent Si(1) atoms. Si(1) is bonded to six equivalent Rh(1) atoms to form distorted corner-sharing SiRh6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
