Materials Data on Dy2TeO2 by Materials Project
Dy2TeO2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Dy3+ is bonded in a 4-coordinate geometry to four equivalent Te2- and four equivalent O2- atoms. All Dy–Te bond lengths are 3.45 Å. All Dy–O bond lengths are 2.25 Å. Te2- is bonded in a distorted body-centered cubic geometry to eight equivalent Dy3+ atoms. O2- is bonded to four equivalent Dy3+ atoms to form a mixture of corner and edge-sharing ODy4 tetrahedra.
