DyCo4B crystallizes in the hexagonal P6/mmm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. In the second Dy site, Dy(2) is bonded in a 18-coordinate geometry to twelve equivalent Co(2) and six equivalent B(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a distorted L-shaped geometry to two equivalent Dy(2), two equivalent Co(1), and two equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Dy(2) and six equivalent Co(2) atoms.
