The crystal structure described by Co3P2(H2O5)2 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 two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with two equivalent Co(2)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and faces with two equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. In the second Co site, Co(2) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share  a cornercorner with one Co(1)O6 octahedra, corners with two equivalent Co(2)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 52-59°. 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 and corners with four equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-54°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted linear geometry to one O(2) and one O(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to one Co(1), two equivalent Co(2), and one H(2) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one P(1) atom. In the third O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Co(2), one P(1), and one H(1) atom. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one P(1) atom. In the fifth O site, O(4) is bonded in a 3-coordinate geometry to one Co(2), one P(1), and one H(1) atom. is represented by the CIF file [CIF]
