Abstract

LiAlGe2O6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.05–2.18 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with three equivalent GeO4 tetrahedra, corners with two equivalent GeO5 trigonal bipyramids, edges with two equivalent AlO6 octahedra, and an edgeedge with one GeO5 trigonal bipyramid. There are a spread of Al–O bond distances ranging from 1.84–2.03 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to five O2- atoms to form distorted GeO5 trigonal bipyramids that share corners with two equivalent AlO6 octahedra, corners with three equivalent GeO4 tetrahedra, and an edgeedge with one AlO6 octahedra. The corner-sharing octahedra tilt angles range from 25–51°. There are a spread of Ge–O bond distances ranging from 1.74–2.39 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with three equivalent AlO6 octahedra and corners with three equivalent GeO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 46–67°. There are a spread of Ge–O bond distancesmore »« less
