“…41,42 Comparing the values of the line width (G) and quadrupolar splitting (∆ EQ ), there are significant differences between the values observed for the FeY and the complexes. The changes in these parameters indicate that the coordination environment around the Fe(III) center was modified after the insertion of the ligand.…”

Recebido em 6/4/11; aceito em 22/11/11; publicado na web em 31/1/12Zeolite-encapsulated complexes have been widely applied in hydrocarbon oxidation catalysis. The "ship-in-a-bottle" encapsulation of iron(III) complexes containing piperazine and piperazine-derivative ligands in zeolite-Y is described. The flexible ligand methodology was employed and the efficiency and reproducibility of the procedure was investigated. The catalysts were characterized employing several techniques and the results indicate the presence of coordinated and uncoordinated iron(III) ions inside and outside the zeolitic cage.

The hydrothermal reaction of CoCl2·6H2O, 1,10-phenanthroline (phen) and K3[Fe(CN)6] in deionized water yielded the title cyanide-bridged trinuclear cluster, [Co2Fe(CN)8(C12H8N2)4]·4H2O or [{CoIII(phen)(CN)4}2{FeII(phen)2}]·4H2O, which contains two CoIII centers and one FeII center linked by cyanide bridges. The combination of coordinative bonds, O—H⋯N and O—H⋯O hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 3.630 (2) Å] results in the stabilization of a supramolecular structure. All uncoordinated water molecules are disordered. Thermogravimetric analysis reveals that the title complex loses the four crystal water molecules at about 333 K, then the anhydrous phase loses no further mass up to about 573 K, above which decomposition occurs.

In den letzten Jahren hat sich gezeigt, dass neben anorganischen Silicaten und Phosphaten auch Carboxylate, Arsenate, Sulfate, Selenate, Selenite, Germanate und Phosphite offene Gerüststrukturen bilden können. Von besonderem Interesse sind die organisch‐anorganischen Hybridverbindungen, die sich aus der Kombination der reichen Koordinationschemie der zentralen Metall‐Ionen vieler dieser Strukturtypen mit der Flexibilität und der Funktionalität organischer Verbindungsglieder (“Linker”) ergeben. Vor allem die Übergangsmetalle scheinen besonders viele Varianten zu liefern, was in den bevorzugten Koordinationsweisen, Ligandengeometrien und Valenzzuständen begründet ist. Außerdem lässt die Kombination der magnetischen Eigenschaften von Übergangsmetallen mit den Kanalstrukturen offener Gerüste interessante Anwendungen erwarten. In diesem Aufsatz werden die Synthesen, Strukturen und Eigenschaften einer Reihe von Übergangsmetallverbindungen mit offenem Gerüst vorgestellt.
