Abstract
LiVSi2O6 is Esseneite structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.07–2.53 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six SiO4 tetrahedra and edges with two equivalent VO6 octahedra. There are a spread of V–O bond distances ranging from 1.96–2.12 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent VO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 34–59°. There is one shorter (1.62 Å) and three longer (1.65 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent VO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–59°. There is one shorter (1.61 Å) and three longer (1.65 Å) Si–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2-more »
