The structure described by Dy12Co7 crystallizes in the monoclinic P2_1/c space group. There are six inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to one Co(2), one Co(3), and two equivalent Co(4) atoms. In the second Dy site, Dy(2) is bonded in a 4-coordinate geometry to one Co(2), one Co(3), and two equivalent Co(4) atoms. In the third Dy site, Dy(3) is bonded to one Co(1), one Co(2), one Co(3), and one Co(4) atom to form distorted corner-sharing DyCo4 tetrahedra. In the fourth Dy site, Dy(4) is bonded in a 5-coordinate geometry to one Co(1), one Co(2), one Co(4), and two equivalent Co(3) atoms. In the fifth Dy site, Dy(5) is bonded in a 5-coordinate geometry to one Co(1), one Co(3), one Co(4), and two equivalent Co(2) atoms. In the sixth Dy site, Dy(6) is bonded in a 5-coordinate geometry to one Co(1), one Co(2), one Co(4), and two equivalent Co(3) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a body-centered cubic geometry to two equivalent Dy(3), two equivalent Dy(4), two equivalent Dy(5), and two equivalent Dy(6) atoms. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to one Dy(1), one Dy(2), one Dy(3), one Dy(4), one Dy(6), two equivalent Dy(5), and one Co(3) atom. In the third Co site, Co(3) is bonded in a 9-coordinate geometry to one Dy(1), one Dy(2), one Dy(3), one Dy(5), two equivalent Dy(4), two equivalent Dy(6), and one Co(2) atom. In the fourth Co site, Co(4) is bonded in a 8-coordinate geometry to one Dy(3), one Dy(4), one Dy(5), one Dy(6), two equivalent Dy(1), and two equivalent Dy(2) atoms. is represented by the CIF card [CIF]
