Materials Data on TiS2N by Materials Project

STiNS is trigonal omega-derived structured and crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three ammonia molecules and three TiS2 sheets oriented in the (0, 0, 1) direction. In each TiS2 sheet, Ti3+ is bonded to six equivalent S2- atoms to form edge-sharing TiS6 octahedra. All Ti–S bond lengths are 2.43 Å. S2- is bonded in a distorted T-shaped geometry to three equivalent Ti3+ atoms.

Materials Data on Ti4S8N by Materials Project

(TiS2)8N2 is trigonal omega-derived structured and crystallizes in the monoclinic Pm space group. The structure is two-dimensional and consists of one ammonia molecule and two TiS2 sheets oriented in the (0, 0, 1) direction. In each TiS2 sheet, Ti+3.75+ is bonded to six S2- atoms to form edge-sharing TiS6 octahedra. There are three shorter (2.42 Å) and three longer (2.44 Å) Ti–S bond lengths. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Ti+3.75+ atoms. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Ti+3.75+ atoms. In the third S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Ti+3.75+ atoms. In the fourth S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Ti+3.75+ atoms.
