The material structure described by Tm2TeO2 crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded in a 4-coordinate geometry to three equivalent Te(1) and four equivalent O(1) atoms. Te(1) is bonded to six equivalent Tm(1) atoms to form distorted TeTm6 pentagonal pyramids that share corners with twelve equivalent O(1)Tm4 tetrahedra, edges with six equivalent Te(1)Tm6 pentagonal pyramids, and edges with six equivalent O(1)Tm4 tetrahedra. O(1) is bonded to four equivalent Tm(1) atoms to form OTm4 tetrahedra that share corners with six equivalent Te(1)Tm6 pentagonal pyramids, corners with six equivalent O(1)Tm4 tetrahedra, edges with three equivalent Te(1)Tm6 pentagonal pyramids, and edges with three equivalent O(1)Tm4 tetrahedra. is represented by the CIF card [CIF]
