SrDy2Co crystallizes in the trigonal R3m space group. Sr(1) is bonded to one Dy(1), one Dy(2), and three equivalent Co(1) atoms to form distorted corner-sharing SrDy2Co3 trigonal bipyramids. The Sr(1)-Dy(1) bond length is 1.95 Å. The Sr(1)-Dy(2) bond length is 1.95 Å. All Sr(1)-Co(1) bond lengths are 3.04 Å. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a linear geometry to one Sr(1) and one Co(1) atom. The Dy(1)-Co(1) bond length is 1.95 Å. In the second Dy site, Dy(2) is bonded in a single-bond geometry to one Sr(1) atom. Co(1) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one Dy(1) atom.
