Materials Data on Y2TeO2 by Materials Project
Y2TeO2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Y3+ is bonded in a 4-coordinate geometry to four equivalent Te2- and four equivalent O2- atoms. All Y–Te bond lengths are 3.46 Å. All Y–O bond lengths are 2.26 Å. Te2- is bonded in a distorted body-centered cubic geometry to eight equivalent Y3+ atoms. O2- is bonded to four equivalent Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra.
