The material described by Sr5Sb3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. In the second Sr site, Sr(2) is bonded to one Sb(2) and four equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing SrSb5 square pyramids. In the third Sr site, Sr(3) is bonded in a 5-coordinate geometry to one Sb(2) and four equivalent Sb(1) atoms. In the fourth Sr site, Sr(4) is bonded to one Sb(2) and four equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing SrSb5 square pyramids. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), two equivalent Sr(3), and two equivalent Sr(4) atoms. In the second Sb site, Sb(2) is bonded to one Sr(2), one Sr(3), one Sr(4), and four equivalent Sr(1) atoms to form distorted edge-sharing SbSr7 pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
