Materials Data on Zn2SiH2O5 by Materials Project
Zn2SiO3(OH)2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional and consists of two water molecules and one Zn4Si2O7(OH)2 framework. In the Zn4Si2O7(OH)2 framework, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three equivalent SiO4 tetrahedra and corners with four equivalent ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.97–2.00 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and corners with six equivalent ZnO4 tetrahedra. All Si–O bond lengths are 1.64 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Zn2+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms.
