DyCuSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the monoclinic P2_1/m space group. Dy(1) is bonded to four equivalent Cu(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form a mixture of edge, face, and corner-sharing DyCu4Sb8 cuboctahedra. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Dy(1), four equivalent Cu(1), and four equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Cu(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Sb(2) atoms.

Dy(1) is bonded to four equivalent Cu(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form a mixture of edge, face, and corner-sharing DyCu4Sb8 cuboctahedra. There are a spread of Dy(1)-Cu(1) bond distances ranging from 3.25-3.32 Å. There are two shorter (3.17 Å) and two longer (3.18 Å) Dy(1)-Sb(1) bond lengths. All Dy(1)-Sb(2) bond lengths are 3.25 Å. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Dy(1), four equivalent Cu(1), and four equivalent Sb(1) atoms. There are two shorter (2.99 Å) and two longer (3.08 Å) Cu(1)-Cu(1) bond lengths. There is one shorter (2.64 Å) and three longer (2.65 Å) Cu(1)-Sb(1) bond lengths. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Cu(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Sb(2) atoms. All Sb(2)-Sb(2) bond lengths are 3.03 Å.
