Oktaedrische Pd2+‐Koordination und ferromagnetische Ordnung in Pd(S2O7)

Abstract: Es ist lange bekannt, dass die elektronische d 8 -Konfiguration des zweiwertigen Palladiums in der Regel zu einer quadratisch-planaren Koordination des Metalls in seinen Verbindungen führt. Nur für Liganden, die zu einer schwachen Ligandenfeldaufspaltung führen, wird auch die oktaedrische Koordination beobachtet. Beispielhaft hierfür kçnnen die Fluoride des Palladiums genannt werden, bei denen sowohl für die bekannten Modifikationen von PdF 2 [1][2][3][4] als auch für die polynären Verbindungen APdF 3 (A = K, … Show more

“…Very recently, K 5 [BA C H T U N G T R E N N U N G (SO 4 ) 4 ] was characterised as the first representative of the borosulfates. The prominent structural feature is a supertetrahedral anion with a central BO 4 tetrahedron surrounded by four SO 4 tetrahedra.…”

“…The prominent structural feature is a supertetrahedral anion with a central BO 4 tetrahedron surrounded by four SO 4 tetrahedra. [1] With a ratio of 1:4 between BO 4 and SO 4 tetrahedra, the supertetrahedral units are not condensed, leading to a charge of À5. Later on, the same unit was found in the two polymorphs of Na 5 [BA C H T U N G T R E N N U N G (SO 4 ) 4 ].…”

“…Nur für Schwachfeldliganden, insbesondere das Fluoridion, tritt gelegentlich eine oktaedrische Koordination auf. Wickleder et al realisierten nun im paramagnetischen Disulfat Pd(S2O7) erstmals die ungewöhnliche, oktaedrische Koordination von Pd2+ durch sechs Sauerstoffdonoren 8. Die Verbindung entsteht durch die Reaktion von elementarem Palladium mit SO3.…”

“…In order to prepare even higher polysulfates we expanded our research to reactions with neat SO 3 , which lead us to partly unprecedented new sulfates and polysulfates. In this way we obtained the first palladium disulfate, Pd(S 2 O 7 ), in which the octahedral oxygen coordination of palladium leads to a ferromagnetic behavior at low temperature 6. Moreover, we presented the first tetrasulfate in the structure of (NO) 2 [S 4 O 13 ]7 and the first complex of this anion in the structure of K 2 [Pd(S 4 O 13 ) 2 ] 8.…”
