EuTi2CdO6F crystallizes in the orthorhombic Imma space group. Eu(1) is bonded to two equivalent O(1), four equivalent O(2), and two equivalent F(1) atoms to form distorted EuO6F2 hexagonal bipyramids that share edges with two equivalent Eu(1)O6F2 hexagonal bipyramids, edges with four equivalent Cd(1)O6F2 hexagonal bipyramids, edges with two equivalent Ti(2)O6 octahedra, and edges with four equivalent Ti(1)O6 octahedra.
