Stabilizing the Homopolycation (I4)2+ with a Hexasulfate in (I4)[S6O19] and a Borosulfate in (I4)[B(S2O7)2]2

Abstract: The reaction of elemental iodine and SO 3 in a sealed glass ampoule yielded a turquoise‐colored solution. At temperatures below 7 °C, deep red crystals of (I 4 )[S 6 O 19 ] grow. With the addition of B 2 O 3 and pyridine‐SO 3 complex red crystals of (I 4 )[B(S 2 O 7 ) 2 … Show more

“…[58,59] The weak coordination behavior was also demonstrated by the stabilization of (I 4 ) 2 + -cations. [60] The latter can also be obtained in presence of a sufficiently powerful oxidizer and weakly coordinating anions such as [AsF 6 ] À and [SbF 6 ] À . [61] The special reaction conditions during the synthesis as well as the weak coordination behavior of the borosulfate anions are most likely also the reason for the stabilization of the cluster-like heteropolycations in [Au 3 Cl 4 ][B(S 2 O 7 ) 2 ] and the chain-like heteropolycations in [Au 2 Cl 4 ][B(S 2 O 7 ) 2 ](SO 3 ).…”

“…oligomeric anions (like nesosilicates), [52,53] infinite chains (like inosilicates), [53,54] layers (like phyllosilicates) [50,55–57] or 3D network structures (like tectosilicates) [58,59] . The weak coordination behavior was also demonstrated by the stabilization of (I 4 ) 2+ ‐cations [60] . The latter can also be obtained in presence of a sufficiently powerful oxidizer and weakly coordinating anions such as [AsF 6 ] − and [SbF 6 ] − [61] .…”

“…B. oligomere Anionen (wie Nesosilicate), [52,53] unendliche Ketten (wie Inosilicate), [54,55] Schichten (wie Phyllosilicate) [50,55–57] oder 3D‐Netzwerk‐Strukturen (wie Tektosilicate) [58,59] . Das schwache Koordinationsverhalten wurde auch durch die Stabilisierung von (I 4 ) 2+ ‐Kationen nachgewiesen [60] . Letztere können auch in Anwesenheit eines geeigneten Oxidationsmittels sowie schwach koordinierender Anionen wie [AsF 6 ] − und [SbF 6 ] − erhalten werden [61] .…”

[61] Die besonderen Reaktionsbedingungen während der Synthese sowie das schwache Koordinationsverhalten der Borosulfat-Anionen sind vermutlich auch der Grund für die Stabilisierung der clusterartigen Heteropolykationen in [Au 3 Cl 4 ][B(S 2 O 7 ) 2 ] und der kettenartigen Heteropolykationen in [Au 2 Cl 4 ][B(S 2 O 7 ) 2 ](SO 3 ).…”
