Synthesis of a Hexachloro Sulfate(IV) Dianion Enabled by Polychloride Chemistry

Abstract: The preparation and structural characterization of [NEt3Me]2[SCl6] is described, which is the first example of a [SCl6]2− dianion and of a halosulfate anion of the type [SxXy]z− in general. This dianion belongs to the group of 14‐valence electron AB6E systems and forms an octahedral structure in the solid‐state. Interestingly, co‐crystallization with CH2Cl2 affords [NEt3Me]2[SCl6]⋅4 CH2Cl2 containing [SCl6]2− dianions with C4v symmetry. As suggested by quantum‐chemical calculations, the distortion of the struc… Show more

“…When [NEt 3 Me][Cl 3 ] is used instead, it could be speculated that SCl 4 is formed as intermediate that further reacts with [NEt 3 Me]Cl to [NEt 3 Me] 2 [SCl 6 ]. This highlights the unique ability of [NEt 3 Me][Cl 3 ] to serve as an chlorination agent while stabilizing unprecedented anions [39] …”

“…Wenn stattdessen [NEt 3 Me][Cl 3 ] verwendet wird, kann vermutet werden, dass SCl 4 als Zwischenprodukt gebildet wird, das mit [NEt 3 Me]Cl zu [NEt 3 Me] 2 [SCl 6 ] weiterreagiert. Dies unterstreicht die einzigartige Fähigkeit von [NEt 3 Me][Cl 3 ], als Chlorierungsmittel zu fungieren und gleichzeitig neuartige Anionen zu stabilisieren [39] …”
