The material structure described by CaTiCo(PO4)3 crystallizes in the trigonal R3c space group. Ca(1) is bonded in a distorted hexagonal planar geometry to three equivalent O(2) and three equivalent O(3) atoms. 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. Co(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. 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 Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-42°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Co(1) and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ca(1), one Ti(1), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ca(1), one Co(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]
