Materials Data on Er2TeO2 by Materials Project

Er2TeO2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Er3+ is bonded in a 4-coordinate geometry to three equivalent Te2- and four equivalent O2- atoms. All Er–Te bond lengths are 3.14 Å. There are one shorter (2.26 Å) and three longer (2.31 Å) Er–O bond lengths. Te2- is bonded in a 6-coordinate geometry to six equivalent Er3+ atoms. O2- is bonded to four equivalent Er3+ atoms to form a mixture of edge and corner-sharing OEr4 tetrahedra.
