The crystal structure described by NaZnSiO4 is Covellite-derived structured and crystallizes in the orthorhombic P2_12_12_1 space group. Na(1) is bonded to one O(2), two equivalent O(1), and two equivalent O(4) atoms to form NaO5 trigonal bipyramids that share corners with three equivalent Zn(1)O4 tetrahedra, corners with five equivalent Si(1)O4 tetrahedra, and corners with four equivalent Na(1)O5 trigonal bipyramids. Zn(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra, corners with four equivalent Si(1)O4 tetrahedra, and corners with three equivalent Na(1)O5 trigonal bipyramids. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra and corners with five equivalent Na(1)O5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1), one Zn(1), and one Si(1) atom to form distorted corner-sharing ONa2ZnSi tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Na(1), one Zn(1), and one Si(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one Si(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Na(1) and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
