PdTel und Pd2SeI3 — die ersten Chalkogenidhalogenide eines Platinmetalles

Abstract: Feld und der Briickenprotonen bei hohem Feld (Tabelle 1) mit der Existenz eines Ringstroms zu vereinbaren ist. Auch das protonenentkoppelte 13C-NMR-Spektrum (Tabelle 1) ist mit dieser Vorstellung in Einklang.

“…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.…”

“…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. “Ordinary” chalcogenide halides like PdITe5, 9 have been found to be electronic conductors. In spite of its diamagnetic properties, PdITe reputedly contains Pd in oxidation state (+III), which is unknown for the binary platinum group metal chalcogenides or halides: PtX 3 (X=Cl, Br, I) are mixed‐valent (+II/+IV) halides 1115.…”

“…[7]. Ein identischer Se±Se-Abstand wurde in Pd 4 Se 2 I 6 gefunden [8]. Zentrale Baueinheiten sind quasitetraedrische Nb 2 Se 2 -Einheiten, die zweifach asymmetrisch la È ngs der Nb±Nb-Kante von zwei I-Atomen verbru È ckt und durch zwei weitere I-Atome mit weiteren Tetraedern verknu È pft sind, so daû eine gewellte Kette mit abwechselnd nach oben und nach unten ausgerichteten Se 2 -Hanteln vorliegt.…”
