DyNi crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two DyNi clusters. Dy(1) is bonded in a distorted single-bond geometry to one Ni(1) atom. The Dy(1)-Ni(1) bond length is 1.25 Å. Ni(1) is bonded in a distorted single-bond geometry to one Dy(1) atom.
