Zn(PO4)2 crystallizes in the orthorhombic Pna2_1 space group. Zn(1) is bonded to one O(1), one O(3), one O(5), and one O(8) atom to form ZnO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. The Zn(1)-O(1) bond length is 1.93 Å. The Zn(1)-O(3) bond length is 1.94 Å. The Zn(1)-O(5) bond length is 1.90 Å. The Zn(1)-O(8) bond length is 1.93 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(4), one O(5), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra. The P(1)-O(3) bond length is 1.49 Å. The P(1)-O(4) bond length is 1.58 Å. The P(1)-O(5) bond length is 1.49 Å. The P(1)-O(7) bond length is 1.57 Å. In the second P site, P(2) is bonded to one O(1), one O(2), one O(6), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra. The P(2)-O(1) bond length is 1.51 Å. The P(2)-O(2) bond length is 1.55 Å. The P(2)-O(6) bond length is 1.58 Å. The P(2)-O(8) bond length is 1.51 Å. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one P(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one P(2) atom. In the seventh O site, O(7) is bonded in a single-bond geometry to one P(1) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Zn(1) and one P(2) atom.
