Materials Data on ZnSO4 by Materials Project

Abstract

ZnSO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent SO4 tetrahedra and edges with two equivalent ZnO6 octahedra. There are a spread of Zn–O bond distances ranging from 1.99–2.33 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 43–54°. There are a spread of S–O bond distances ranging from 1.48–1.52 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one S6+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Zn2+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one S6+ atom.
