The material described by Co2CPH2O7 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one O(2), one O(6), one O(7), and two equivalent O(3) atoms to form distorted CoO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with two equivalent Co(2)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra,  an edgeedge with one Co(2)O6 octahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-60°. In the second Co site, Co(2) is bonded to one O(2), one O(3), one O(5), one O(7), and two equivalent O(4) atoms to form distorted CoO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with two equivalent Co(2)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra,  an edgeedge with one Co(1)O6 octahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-59°. C(1) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(7) atom. 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 Co(1)O6 octahedra, corners with two equivalent Co(2)O6 octahedra,  an edgeedge with one Co(1)O6 octahedra, and  an edgeedge with one Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-57°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) and one O(6) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) and one O(6) atom. There are seven inequivalent O sites. In the first O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Co(2), two equivalent Co(1), and one P(1) atom. In the second O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Co(2) and one P(1) atom. In the third O site, O(5) is bonded in a 3-coordinate geometry to one Co(2), one C(1), and one H(2) atom. In the fourth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Co(1), one H(1), and one H(2) atom.
