Materials Data on Na2BeSiO4 by Materials Project
Abstract
Na2BeSiO4 crystallizes in the monoclinic P2_1/c 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 O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.70 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.33–2.69 Å. Be2+ is bonded to four O2- atoms to form BeO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra and an edgeedge with one BeO4 tetrahedra. There is two shorter (1.61 Å) and two longer (1.69 Å) Be–O bond length. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent BeO4 tetrahedra. There is one shorter (1.63 Å) and three longer (1.66 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Na1+, two equivalent Be2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+, one Be2+, and one Si4+ atom. In the thirdmore »
