Dy5CoSb2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Dy sites. In the first Dy site, Dy is bonded to one Co and four equivalent Sb atoms to form a mixture of distorted face, edge, and corner-sharing DyCoSb4 trigonal bipyramids. The Dy–Co bond length is 2.70 Å. All Dy–Sb bond lengths are 3.15 Å. In the second Dy site, Dy is bonded to one Co and four equivalent Sb atoms to form a mixture of distorted face, edge, and corner-sharing DyCoSb4 trigonal bipyramids. The Dy–Co bond length is 3.02 Å. All Dy–Sb bond lengths are 3.12 Å. In the third Dy site, Dy is bonded to one Co and four equivalent Sb atoms to form a mixture of distorted edge and corner-sharing DyCoSb4 trigonal bipyramids. The Dy–Co bond length is 2.70 Å. There are two shorter (3.18 Å) and two longer (3.23 Å) Dy–Sb bond lengths. In the fourth Dy site, Dy is bonded in a 5-coordinate geometry to two equivalent Co and three equivalent Sb atoms. There are one shorter (2.74 Å) and one longer (2.85 Å) Dy–Co bond lengths. There are a spread of Dy–Sb bond distances ranging from 3.31–3.52 Å. Co is bonded to seven Dy atoms to form distorted edge-sharing CoDy7 pentagonal bipyramids. Sb is bonded in a 9-coordinate geometry to nine Dy atoms.
