Abstract

Na(H2O)6Zn4H6SO10Cl crystallizes in the trigonal P-3 space group. The structure is two-dimensional and consists of two sodium;hexahydrate molecules and one Zn4H6SO10Cl sheet oriented in the (0, 0, 1) direction. In the Zn4H6SO10Cl sheet, there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share a cornercorner with one SO4 tetrahedra, corners with two equivalent ZnClO3 tetrahedra, and edges with five equivalent ZnO6 octahedra. There are a spread of Zn–O bond distances ranging from 2.05–2.51 Å. In the second Zn2+ site, Zn2+ is bonded to three equivalent O2- and one Cl1- atom to form corner-sharing ZnClO3 tetrahedra. The corner-sharing octahedra tilt angles range from 57–60°. All Zn–O bond lengths are 1.99 Å. The Zn–Cl bond length is 2.29 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All S–O bond lengths are 1.50 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Zn2+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Zn2+ and one H1+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Zn2+ and one S6+ atom. Cl1- is bonded in a single-bond geometry to one Zn2+ atom.
