Co3Te2(PO7)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra and edges with two equivalent Co(1)O6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(3), and two equivalent O(4) atoms to form PO4 tetrahedra that share  a cornercorner with one Co(2)O6 octahedra and corners with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-50°. Te(1) is bonded in a 5-coordinate geometry to one O(5), two equivalent O(2), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Co(2) and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Co(2) and one Te(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Co(1), one P(1), and one Te(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to two equivalent Co(1) and one Te(1) atom.
