Materials Data on Na2ZnSiO4 by Materials Project
Na2ZnSiO4 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 tetrahedra that share corners with four equivalent NaO4 tetrahedra, corners with four equivalent ZnO4 tetrahedra, and corners with four equivalent SiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.33–2.38 Å. In the second Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share corners with four equivalent NaO4 tetrahedra, corners with four equivalent ZnO4 tetrahedra, and corners with four equivalent SiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.28–2.34 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra and corners with eight NaO4 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 corners with four equivalent ZnO4 tetrahedra and corners with eight NaO4 tetrahedra. There is two shorter (1.65 Å) and two longer (1.66 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Na1+, one Zn2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one Zn2+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two Na1+, one Zn2+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one Zn2+, and one Si4+ atom.
