description: Na2ZnP(H5O4)3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Na2ZnP(H5O4)3 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent NaO6 octahedra, corners with two equivalent ZnO4 tetrahedra, and an edgeedge with one NaO6 octahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Na–O bond distances ranging from 2.39–2.65 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form edge-sharing NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.38–2.51 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with two equivalent NaO6 octahedra, corners with two equivalent ZnO4 tetrahedra, and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 60–79°. There are a spread of Zn–O bond distances ranging from 1.97–1.99 Å.
