The structure described by Co2(OH)PO4 crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(4), two equivalent O(1), and two equivalent O(3) atoms to form CoO5 trigonal bipyramids that share corners with four equivalent Co(2)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and  an edgeedge with one Co(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 56-73°. In the second Co site, Co(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra, corners with four equivalent Co(1)O5 trigonal bipyramids, and edges with two equivalent Co(2)O6 octahedra. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with four equivalent Co(2)O6 octahedra and corners with four equivalent Co(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 54-62°. H(1) is bonded in a single-bond geometry to one O(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one Co(1), two equivalent Co(2), and one H(1) atom. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Co(1) and one P(1) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Co(2) and one P(1) atom. In the fourth O site, O(3) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one P(1) atom. is represented by the CIF card [CIF]
