DyCuS2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Dy3+ is bonded to six S2- atoms to form DyS6 octahedra that share corners with four equivalent DyS6 octahedra, corners with six equivalent CuS4 tetrahedra, edges with four equivalent DyS6 octahedra, and edges with three equivalent CuS4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Dy–S bond distances ranging from 2.66–2.81 Å. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with six equivalent DyS6 octahedra, corners with two equivalent CuS4 tetrahedra, edges with three equivalent DyS6 octahedra, and edges with two equivalent CuS4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–59°. There are a spread of Cu–S bond distances ranging from 2.30–2.43 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to three equivalent Dy3+ and three equivalent Cu1+ atoms to form distorted edge-sharing SDy3Cu3 octahedra. In the second S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Dy3+ and one Cu1+ atom.
