CoPO4 crystallizes in the tetragonal I-42m space group. Co(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form CoO4 trigonal pyramids that share corners with four equivalent P(1)O4 tetrahedra. The Co(1)-O(2) bond length is 1.89 Å. The Co(1)-O(3) bond length is 1.97 Å. Both Co(1)-O(1) bond lengths are 1.88 Å. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Co(1)O4 trigonal pyramids. The P(1)-O(2) bond length is 1.56 Å. The P(1)-O(3) bond length is 1.43 Å. Both P(1)-O(1) bond lengths are 1.53 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 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 distorted linear 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 4.33 A, density 2.06 g/cm3, surface area 2091.26 m2/g, accessible volume 0.24 cm3/g
