LiSiBiO4 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent BiO6 octahedra and corners with four equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 59–78°. There are a spread of Li–O bond distances ranging from 1.88–2.08 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent BiO6 octahedra and corners with four equivalent LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–56°. There is three shorter (1.65 Å) and one longer (1.67 Å) Si–O bond length. There are three inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.34 Å) and three longer (2.49 Å) Bi–O bond lengths. In the second Bi3+ site, Bi3+ is bonded to six O2- atoms to form distorted BiO6 octahedra that share corners with six equivalent LiO4 tetrahedra and corners with six equivalent SiO4 tetrahedra. There are three shorter (2.27 Å) and three longer (2.64 Å) Bi–O bond lengths. In the third Bi3+ site, Bi3+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Bi–O bond lengths are 2.19 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Si4+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Si4+, and one Bi3+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+, one Si4+, and two Bi3+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Si4+, and one Bi3+ atom.
