NaZnPO4 is Chalcostibite-derived structured and crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), and two equivalent O(2) atoms. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. 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 Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Na(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Na(1), one Zn(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Na(1), one Zn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Na(1), one Zn(1), and one P(1) atom.
