The structure described by Dy2B4C crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 2-coordinate geometry to six equivalent B(1) and two equivalent C(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one B(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a single-bond geometry to two equivalent B(1) and one C(1) atom. C(1) is bonded to four equivalent Dy(1) and two equivalent B(2) atoms to form distorted edge-sharing CDy4B2 octahedra. is represented by the CIF file [CIF]
