Title: Materials Data on Li2MgB12(H4O7)4 by Materials Project

Abstract

Li2MgB12(H4O7)4 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Li2MgB12(H4O7)4 sheet oriented in the (1, 0, 0) direction. Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share a cornercorner with one MgO6 octahedra and a cornercorner with one BO4 tetrahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Li–O bond distances ranging from 1.93–2.05 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six BO4 tetrahedra and corners with two equivalent LiO4 trigonal pyramids. There are a spread of Mg–O bond distances ranging from 2.02–2.36 Å. There are six inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one MgO6 octahedra, corners with two BO4 tetrahedra, and a cornercorner with one LiO4 trigonal pyramid.
