The material structure described by Er5Sb3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Er sites. In the first Er site, Er(1) is bonded in a 6-coordinate geometry to two equivalent Sb(1) and four equivalent Sb(2) atoms. In the second Er site, Er(2) is bonded in a 5-coordinate geometry to two equivalent Sb(1) and three equivalent Sb(2) atoms. In the third Er site, Er(3) is bonded in a 5-coordinate geometry to one Sb(1) and four equivalent Sb(2) atoms. In the fourth Er site, Er(4) is bonded to one Sb(1) and four equivalent Sb(2) atoms to form distorted edge-sharing ErSb5 square pyramids. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to one Er(3), one Er(4), two equivalent Er(1), and four equivalent Er(2) atoms. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(3), two equivalent Er(4), and three equivalent Er(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
