The crystal structure described by Ti2Co(PO5)2 crystallizes in the monoclinic P2_1/c space group. Ti(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form distorted TiO6 octahedra that share  a cornercorner with one Co(1)O6 octahedra, corners with two equivalent Ti(1)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and  a faceface with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-51°. Co(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and faces with two equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles are 51°. P(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra and corners with four equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-49°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one Co(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ti(1) and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ti(1), one Co(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Ti(1), one Co(1), and one P(1) atom. In the fifth O site, O(5) 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]
