The material structure described by ErIrSi crystallizes in the orthorhombic Pnma space group. Er(1) is bonded in a 11-coordinate geometry to six equivalent Ir(1) and five equivalent Si(1) atoms. Ir(1) is bonded in a 10-coordinate geometry to six equivalent Er(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Er(1) and four equivalent Ir(1) atoms. is represented by the CIF file [CIF]
