Zn(PO4)2 crystallizes in the orthorhombic Fdd2 space group. Zn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. Both Zn(1)-O(1) bond lengths are 1.93 Å. Both Zn(1)-O(2) bond lengths are 1.93 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 two equivalent Zn(1)O4 tetrahedra. The P(1)-O(1) bond length is 1.53 Å. The P(1)-O(2) bond length is 1.49 Å. The P(1)-O(3) bond length is 1.54 Å. The P(1)-O(4) bond length is 1.58 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one P(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one P(1) atom. Linkers: 16 [O]P([O])([O])=O. Metal clusters: 8 [Zn]. The MOF has largest included sphere 5.33 A, density 1.42 g/cm3, surface area 3248.77 m2/g, accessible volume 0.32 cm3/g
