CoPO4 crystallizes in the tetragonal P4_2/n space group. Co(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CoO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. The Co(1)-O(1) bond length is 1.94 Å. The Co(1)-O(2) bond length is 1.96 Å. The Co(1)-O(3) bond length is 1.95 Å. The Co(1)-O(4) bond length is 1.91 Å. 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 four equivalent Co(1)O4 tetrahedra. The P(1)-O(1) bond length is 1.52 Å. The P(1)-O(2) bond length is 1.51 Å. The P(1)-O(3) bond length is 1.53 Å. The P(1)-O(4) bond length is 1.52 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Co(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Co(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Co(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one P(1) atom. Linkers: 8 [O]P([O])([O])=O. Metal clusters: 8 [Co]. The MOF has largest included sphere 3.95 A, density 2.12 g/cm3, surface area 2300.00 m2/g, accessible volume 0.21 cm3/g
