The corner-sharing octahedral tilt angles are 58°. There are a spread of Si–O bond distances ranging from 1.61–1.67 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one VO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of Si–O bond distances ranging from 1.60–1.67 Å. In the fourth Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two VO6 octahedra and corners with two SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 28–46°. There are a spread of Si–O bond distances ranging from 1.61–1.68 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded to two Li1+, one V3+, and one Si4+ atom to form distorted corner-sharing OLi2VSi tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Si4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the seventh O2- site, O2- is bonded to two Li1+, one V3+, and one Si4+ atom to form distorted corner-sharing OLi2VSi tetrahedra. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one Si4+ atom.
