The material described by DyBr2 is trigonal omega-like structured and crystallizes in the tetragonal P4_2/mnm space group. Dy(1) is bonded to six equivalent Br(1) atoms to form a mixture of corner and edge-sharing DyBr6 octahedra. The corner-sharing octahedral tilt angles are 39°. Br(1) is bonded in a 3-coordinate geometry to three equivalent Dy(1) atoms. is represented by the CIF card [CIF]
