Materials Data on Yb2TeO2 by Materials Project
Yb2TeO2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Yb3+ is bonded to three equivalent Te2- and four equivalent O2- atoms to form distorted YbTe3O4 trigonal pyramids that share corners with three equivalent YbTe3O4 trigonal pyramids, corners with nine equivalent OYb4Te3 trigonal pyramids, edges with three equivalent OYb4Te3 trigonal pyramids, edges with twelve equivalent YbTe3O4 trigonal pyramids, and a faceface with one OYb4Te3 trigonal pyramid. All Yb–Te bond lengths are 3.67 Å. There are three shorter (2.18 Å) and one longer (2.27 Å) Yb–O bond lengths. Te2- is bonded in a 6-coordinate geometry to six equivalent Yb3+, six equivalent Te2-, and six equivalent O2- atoms. All Te–Te bond lengths are 3.73 Å. All Te–O bond lengths are 3.94 Å. O2- is bonded to four equivalent Yb3+ and three equivalent Te2- atoms to form OYb4Te3 trigonal pyramids that share corners with three equivalent OYb4Te3 trigonal pyramids, corners with nine equivalent YbTe3O4 trigonal pyramids, edges with three equivalent YbTe3O4 trigonal pyramids, edges with twelve equivalent OYb4Te3 trigonal pyramids, and a faceface with one YbTe3O4 trigonal pyramid.
