Zn3(PO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to five O2- atoms to form distorted ZnO5 trigonal bipyramids that share corners with three equivalent ZnO6 octahedra, corners with five equivalent PO4 tetrahedra, and an edgeedge with one ZnO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 58–77°. There are a spread of Zn–O bond distances ranging from 2.00–2.23 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share corners with six equivalent PO4 tetrahedra and corners with six equivalent ZnO5 trigonal bipyramids. There are a spread of Zn–O bond distances ranging from 2.06–2.39 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and corners with five equivalent ZnO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 50–60°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Zn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+ and one P5+ atom.
