The material described by EuCrTeO6 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/c space group. Eu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form EuO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and corners with six equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-54°. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra and edges with three equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-54°. Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TeO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra and edges with three equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Eu(1), one Cr(1), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Eu(1), one Cr(1), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Eu(1), one Cr(1), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
