Materials Data on Na4Zr2(SiO4)3 by Materials Project
Na4Zr2Si3O12 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Na–O bond lengths are 2.50 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.57 Å) and two longer (2.67 Å) Na–O bond lengths. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six equivalent SiO4 tetrahedra. There are three shorter (2.06 Å) and three longer (2.17 Å) Zr–O bond lengths. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 26–40°. All Si–O bond lengths are 1.64 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Na1+, one Zr4+, and one Si4+ atom to form a mixture of distorted face, edge, and corner-sharing ONa3ZrSi trigonal bipyramids. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one Zr4+, and one Si4+ atom.
