The structure described by CdFeTi(PO4)3 crystallizes in the trigonal R3c space group. Ti(1) is bonded to three equivalent O(2) and three equivalent O(4) atoms to form TiO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. Fe(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form FeO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. Cd(1) is bonded in a distorted hexagonal planar geometry to three equivalent O(2) and three equivalent O(3) atoms. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent Ti(1)O6 octahedra and corners with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 25-44°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ti(1), one Cd(1), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Fe(1), one Cd(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Ti(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
