Abstract

Li2MgBr4 crystallizes in the tetragonal P4_322 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six Br1- atoms to form LiBr6 octahedra that share corners with two equivalent LiBr6 octahedra, corners with four equivalent MgBr6 octahedra, edges with two equivalent MgBr6 octahedra, and edges with six LiBr6 octahedra. The corner-sharing octahedra tilt angles range from 2–10°. There are two shorter (2.15 Å) and four longer (2.17 Å) Li–Br bond lengths. In the second Li1+ site, Li1+ is bonded to six Br1- atoms to form LiBr6 octahedra that share corners with two equivalent LiBr6 octahedra, edges with four equivalent MgBr6 octahedra, and edges with six LiBr6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are two shorter (2.11 Å) and four longer (2.26 Å) Li–Br bond lengths. Mg2+ is bonded to six Br1- atoms to form MgBr6 octahedra that share corners with four equivalent LiBr6 octahedra, edges with two equivalent MgBr6 octahedra, and edges with six LiBr6 octahedra. The corner-sharing octahedra tilt angles range from 2–10°. There are four shorter (2.29 Å) and two longer (2.31 Å) Mg–Br bond lengths. There are two inequivalent Br1- sites. In themore »« less
