LiNaZnP2O7 crystallizes in the orthorhombic C222_1 space group. Na(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form NaO5 square pyramids that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent Zn(1)O4 tetrahedra, and corners with six equivalent P(1)O4 tetrahedra. Li(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form LiO4 tetrahedra that share corners with two equivalent Na(1)O5 square pyramids, corners with two equivalent Zn(1)O4 tetrahedra, and corners with four equivalent P(1)O4 tetrahedra. Zn(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form ZnO4 tetrahedra that share corners with two equivalent Na(1)O5 square pyramids, corners with two equivalent Li(1)O4 tetrahedra, and corners with four equivalent P(1)O4 tetrahedra.
