The crystal structure described by NaP(WO4)2 crystallizes in the monoclinic P2_1/m space group. Na(1) is bonded in a 9-coordinate geometry to one O(2), two equivalent O(3), two equivalent O(5), and four equivalent O(1) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(5), one O(6), two equivalent O(1), and two equivalent O(3) atoms to form WO6 octahedra that share corners with three equivalent W(2)O6 octahedra and corners with three equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 3-15°. In the second W site, W(2) is bonded to one O(2), one O(6), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra, corners with three equivalent W(1)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 0-15°. P(1) is bonded to one O(2), one O(5), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one W(2)O6 octahedra and corners with three equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 18-44°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent Na(1), one W(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(1), one W(2), and one P(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Na(1), one W(1), and one W(2) atom. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent W(2) atoms. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Na(1), one W(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a linear geometry to one W(1) and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
