Abstract

en

Ba(CF3SO3)2 reacts with the O-donor ligand THF to yield the coordination compound equation image{[Ba(OTf)2(thf)3]2[Ba(OTf)2(thf)2]} (1) (OTf = CF3SO3). The title compound can be described as a one-dimensional excerpt from the higher-dimensional crystal structure of Ba(CF3SO3)2, stabilized by THF. This example for the concept of formally “cutting out” structural elements from a three-dimensional solid state compound confirms and can be compared to the case of the structural “genealogy tree” of BaI2. This could be an efficient approach for new materials with highly anisotropic properties.

Synthese und Kristallstruktur der eindimensionalen polymeren Verbindung urn:x-wiley:00442313:media:ZAAC1626:tex2gif-stack-2{[Ba(OTf)2(thf)3]2[Ba(OTf)2(thf)2]} (OTf = CF3SO3) – Ausschnitte einer drei-dimensionalen Struktur als Zugang zu neuen Materialien?

Ba(CF3SO3)2 reagiert mit dem O-Donorliganden THF zur Koordinationsverbindung equation image{[Ba(OTf)2(thf)3]2[Ba(OTf)2(thf)2]} (1) (OTf = CF3SO3). Die Titelverbindung kann als eindimensionaler Aussschnitt aus der höherdimensionalen Kristallstruktur von Ba(CF3SO3)2, stabilisiert durch THF, beschrieben werden. Dieses Beispiel für das Konzept des „Herausschneidens”︁ von Strukturelementen aus dem dreidimensionalen Festkörper bestätigt den Fall des strukturellen Stammbaums von BaI2 und kann damit verglichen werden. Dies könnte einen neuen Zugang zur Synthese neuer Materialien mit höchst anisotropen Eigenschaften darstellen.
