Materials Data on NaAl6Fe3Si6B3H3O30F by Materials Project
Abstract
NaFe3Al6B3Si6H3O30F crystallizes in the trigonal R3m space group. The structure is three-dimensional. Na1+ is bonded in a 10-coordinate geometry to nine O2- and one F1- atom. There are a spread of Na–O bond distances ranging from 2.49–2.82 Å. The Na–F bond length is 2.69 Å. Fe2+ is bonded to five O2- and one F1- atom to form distorted FeO5F octahedra that share corners with two equivalent SiO4 tetrahedra, edges with two equivalent FeO5F octahedra, and edges with two equivalent AlO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.04–2.39 Å. The Fe–F bond length is 2.21 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share a cornercorner with one AlO6 octahedra, corners with three equivalent SiO4 tetrahedra, an edgeedge with one FeO5F octahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of Al–O bond distances ranging from 1.88–1.99 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.39 Å) B–O bond length. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with onemore »
