Title: Materials Data on Na2Zn(SiO3)2 by Materials Project

Abstract

Na2ZnSi2O6 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.28–2.60 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra. There is two shorter (1.96 Å) and two longer (1.99 Å) Zn–O bond length. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent ZnO4 tetrahedra and corners with two equivalent SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.61–1.68 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Zn2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+ and two equivalent Si4+ atoms. In the third O2- site, O2- is bonded to two equivalent Na1+, one Zn2+, and one Si4+ atom to form distorted corner-sharing ONa2ZnSi trigonal pyramids.
