In the third Ti+3.83+ site, Ti+3.83+ is bonded to six S2- atoms to form TiS6 octahedra that share corners with three equivalent AgS6 octahedra and edges with six TiS6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are a spread of Ti–S bond distances ranging from 2.41–2.45 Å. In the fourth Ti+3.83+ site, Ti+3.83+ is bonded to six S2- atoms to form TiS6 octahedra that share corners with three equivalent AgS6 octahedra and edges with six TiS6 octahedra. The corner-sharing octahedra tilt angles range from 46–48°. There are a spread of Ti–S bond distances ranging from 2.41–2.45 Å. In the fifth Ti+3.83+ site, Ti+3.83+ is bonded to six S2- atoms to form TiS6 octahedra that share edges with six TiS6 octahedra and a faceface with one AgS6 octahedra. There are a spread of Ti–S bond distances ranging from 2.40–2.48 Å. In the sixth Ti+3.83+ site, Ti+3.83+ is bonded to six S2- atoms to form TiS6 octahedra that share corners with three equivalent AgS6 octahedra and edges with six TiS6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are a spread of Ti–S bond distances ranging from 2.41–2.45 Å. Ag1+ is bonded to six S2- atoms to form AgS6 octahedra that share corners with twelve TiS6 octahedra and faces with two TiS6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There are one shorter (2.68 Å) and five longer (2.69 Å) Ag–S bond lengths. There are twelve inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted T-shaped geometry to three Ti+3.83+ atoms.
