Intensely red, moisture‐sensitive crystals of [(TiCl 2 )(1,3‐P 2 S 8 )] 2 were obtained by the reaction of TiCl 4 and P 4 S 10 at room temperature. The crystal structure determination revealed molecules formally consisting of two units of the anion [1,3‐P 2 S 8 ] 2– connected with two [TiCl 2 ] 2+ cations resulting in the ring‐shaped [(TiCl 2 )(1,3‐P 2 S 8 )] 2 . The thiophosphate [1,3‐P 2 S 8 ] 2– forms a six‐membered ring and has a rather uncommon constitution among the multitude of anionic phosphorus sulfides and selenides.
