Materials Data on Na2CaSiO4 by Materials Project
Na2CaSiO4 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted trigonal planar geometry to six equivalent O2- atoms. There are three shorter (2.39 Å) and three longer (2.89 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Na–O bond lengths are 2.31 Å. Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.24–2.63 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.63 Å) and three longer (1.66 Å) Si–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Ca2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+, two equivalent Ca2+, and one Si4+ atom.
