Li2Ti3BiO8 is Marcasite-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. Ti(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing TiO6 octahedra. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Ti(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent Ti(1) atoms.
