Description / Table of Contents:
Modification of Layer Silicates by Sterically Demanding Metal Complexes: Synthesis and Intercalation of the Square Planar Complexes [Cu(bppep)(H2O)](ClO4)2 and [Ni(bppep)(Cl)]Cl (bppep = 2,6-Bis[1-phenyl-1-(pyridine-2-yl)ethyl]pyridine) in HectoriteSodium-aqua hectorite reacts with [Cu(bppep)(H2O)](ClO4)2 and [Ni(bppep)(Cl)]Cl with exchange of the sodium-aqua cations against the complex cations [Cu(bppep)(H2O)]2+ and [Ni(bppep)(Cl)]+, respectively. In addition, cation-anion pairs of [Cu(bppep)(H2O)](ClO4)2 and [Ni(bppep)(Cl)]Cl are also intercalated between the hectorite layers (intersalation). On the other hand, it is possible to synthesize [Cu(bppep)(H2O)]2+ or [Ni(bppep)(H2O)]2+ modified hectorites without additional ion-pair intercalation (intersalation) by reaction of nickel- and copper-hectorites with the bppep ligand.
Notes:
Die Umsetzung von Na+(aq)-Hectorit mit [Cu(bppep)(H2O)](ClO4)2 und [Ni(bppep)(Cl)]Cl führt zum Austausch der Na+(aq)-Ionen gegen die Komplexkationen [Cu(bppep)(H2O)]2+ und [Ni(bppep)(Cl)]+. Zusätzlich werden die Kation-Anion-Paare [Cu(bppep)(H2O)](ClO4)2 und [Ni(bppep)(Cl)]Cl zwischen den Hectoritschichten intercaliert (Intersalation). Andererseits ist es möglich, [Cu(bppep)(H2O)]2+ oder [Ni(bppep)(H2O)]2+-modifizierte Hectorite ohne zusätzliche Ionenpaar-Intercalation (Intersalation) durch Reaktion der Cu2+ (aq)- und Ni2+ (aq)-Hectorite mit dem bppep-Ligand zu synthetisieren.
