Title: Materials Data on Na4Al2GaSi3BrO12 by Materials Project

Abstract

Na4GaAl2Si3O12Br crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to three O2- and one Br1- atom to form distorted NaBrO3 tetrahedra that share a cornercorner with one AlO4 tetrahedra, corners with two equivalent GaO4 tetrahedra, corners with three NaBrO3 tetrahedra, and corners with three SiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.32–2.39 Å. The Na–Br bond length is 2.89 Å. In the second Na1+ site, Na1+ is bonded to three O2- and one Br1- atom to form distorted NaBrO3 tetrahedra that share a cornercorner with one GaO4 tetrahedra, corners with two AlO4 tetrahedra, corners with three NaBrO3 tetrahedra, and corners with three SiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.31–2.39 Å. The Na–Br bond length is 2.90 Å. In the third Na1+ site, Na1+ is bonded to three O2- and one Br1- atom to form distorted NaBrO3 tetrahedra that share corners with three NaBrO3 tetrahedra, corners with three AlO4 tetrahedra, and corners with three SiO4 tetrahedra.
