“…Low-temperature solvothermal synthesis has proven to be a fruitful preparative method for gaining access to ternary chalcogen halogen compounds of the platinum group metals with unforeseen structural features and intricate bonding interactions and physical properties. [1][2][3][4][5][6][7][8][9][10] Halogen-rich compounds, as for instance [PdBr 2 A C H T U N G T R E N N U N G (TeBr 2 ) 2 ] [1] or [PtCl 4 -A C H T U N G T R E N N U N G (SeCl 4 ) 2 ], [2] exhibit neutral chalcogen di-or tetrahalide species coordinating to the metal atoms, whereas phases that contain less halogen, for example, [Pd 8 Cl 8 (S 2 ) 4 ], [3] [Pd 6 Cl 6 (S 2 ) 3 ] [4] or [Pd 4 I 6 Se 2 ] [5] usually contain dichalcogenide dumbbells. If the phases are rich in chalcogen, like [PdCl 2 Se 6 ] , [6] [PdBr 2 Se 6 ], [6,7] or [PdCl 2 Se 8 ], [8] neutral chalcogen moieties are coordinating to the metal atoms.…”
