Materials Data on Na(SiO2)3 by Materials Project

Na(SiO2)3 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na is bonded in a distorted hexagonal planar geometry to three equivalent O atoms. All Na–O bond lengths are 2.24 Å. Si is bonded to four O atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.64–1.66 Å. There are three inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent Si atoms. In the second O site, O is bonded in a linear geometry to two equivalent Si atoms. In the third O site, O is bonded in a distorted trigonal planar geometry to one Na and two equivalent Si atoms.
