Abstract

EuTi2CdO6F crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Eu3+ is bonded to six O2- and two equivalent F1- atoms to form distorted EuO6F2 hexagonal bipyramids that share edges with two equivalent EuO6F2 hexagonal bipyramids, edges with four equivalent CdO6F2 hexagonal bipyramids, and edges with six TiO6 octahedra. There are four shorter (2.51 Å) and two longer (2.55 Å) Eu–O bond lengths. Both Eu–F bond lengths are 2.28 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six TiO6 octahedra, edges with two equivalent CdO6F2 hexagonal bipyramids, and edges with four equivalent EuO6F2 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 47–49°. There is two shorter (1.97 Å) and four longer (1.98 Å) Ti–O bond length. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six TiO6 octahedra, edges with two equivalent EuO6F2 hexagonal bipyramids, and edges with four equivalent CdO6F2 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 45–47°. There is four shorter (1.98 Å) and two longer (2.00 Å) Ti–O bond length. Cd2+ ismore »« less
