Dy2O2Se is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 4-coordinate geometry to four equivalent Se(1) and four equivalent O(1) atoms. Se(1) is bonded in a body-centered cubic geometry to eight equivalent Dy(1) atoms. O(1) is bonded to four equivalent Dy(1) atoms to form a mixture of edge and corner-sharing ODy4 tetrahedra.
