TiI3 crystallizes in the hexagonal P6_3/mcm space group. The structure is one-dimensional and consists of one TiI3 ribbon oriented in the (0, 0, 1) direction. Ti3+ is bonded to six equivalent I1- atoms to form face-sharing TiI6 octahedra. All Ti–I bond lengths are 2.80 Å. I1- is bonded in a 2-coordinate geometry to two equivalent Ti3+ atoms.
TiI3 crystallizes in the orthorhombic Pmmn space group. The structure is one-dimensional and consists of two TiI3 ribbons oriented in the (1, 0, 0) direction. Ti3+ is bonded to six I1- atoms to form face-sharing TiI6 octahedra. There are a spread of Ti–I bond distances ranging from 2.75–2.87 Å. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in a 2-coordinate geometry to two equivalent Ti3+ atoms. In the second I1- site, I1- is bonded in a distorted L-shaped geometry to two equivalent Ti3+ atoms. In the third I1- site, I1- is bonded in a 2-coordinate geometry to two equivalent Ti3+ atoms. In the fourth I1- site, I1- is bonded in a distorted L-shaped geometry to two equivalent Ti3+ atoms.
