The structure described by Dy2Co7B3 crystallizes in the hexagonal P6/mmm space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 18-coordinate geometry to one Dy(2), six equivalent Co(1), six equivalent Co(2), and six equivalent B(1) atoms. In the second Dy site, Dy(2) is bonded in a 20-coordinate geometry to two equivalent Dy(1), twelve equivalent Co(1), and six equivalent B(2) atoms. In the third Dy site, Dy(3) is bonded in a 6-coordinate geometry to six equivalent Co(3) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted square co-planar geometry to two equivalent Dy(1), two equivalent Dy(2), two equivalent B(1), and two equivalent B(2) atoms. In the second Co site, Co(2) is bonded in a distorted L-shaped geometry to two equivalent Dy(1), two equivalent Co(3), and two equivalent B(1) atoms. In the third Co site, Co(3) is bonded in a 9-coordinate geometry to three equivalent Dy(3) and six equivalent Co(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to three equivalent Dy(1), three equivalent Co(1), and three equivalent Co(2) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to three equivalent Dy(2) and six equivalent Co(1) atoms. is represented by the CIF card [CIF]
