Abstract

One-pot self-assembly reactions of the polyphosphorus complex [Cp*Fe(η5-P5)] (A), a coinage metal salt AgSbF6, and flexible aliphatic dinitriles NC(CH2)xCN (x=1–10) yield 1D, 2D, and 3D coordination polymers. The seven-membered backbone of the dinitrile was experimentally found as the borderline for the self-assembly system furnishing products of different kinds. At x<7, various rather simple polymers are exclusively formed possessing either 0D or 1D Ag/A structural motifs connected by dinitrile spacers, while at x≥7, the self-assembly switches to unprecedented extraordinary 3D networks of nano-sized host–guest assemblies (SbF6)@[(A)9Ag11]11+ (x=7) or (A)@[(A)12Ag12]12+ (x=8–10) linked by dinitriles. The polycationic nodes represent the first superspheres based on A and silver and are host–guest able. All products are characterized by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. The assemblies [(A)12Ag12]12+ were visualized by transmission electron microscopy.
Eintopf-Selbstorganisationsreaktionen des Polyphosphor-Komplexes [Cp*Fe(η5-P5)] (A), des Münzmetallsalzes AgSbF6 und flexibler aliphatischer Dinitrile NC(CH2)xCN (x=1–10) geben 1D-, 2D- und 3D-Koordinationspolymere. Die siebengliedrige Kette eines Dinitrils wurde experimentell als Grenze für das Selbstorganisationssystem zur Erzeugung verschiedenartiger Produkte detektiert. Bei x<7 werden ausschließlich verschiedene, eher einfache Polymere gebildet, die entweder 0D- oder 1D-Ag/A-Strukturmotive besitzen, die durch Dinitril-Linker verbunden sind, während bei x≥7 die Selbstorganisation zu völlig neuen außergewöhnlichen, durch Nitrile verbundenen 3D-Netzwerken nano-dimensionierter Wirt/Gast-Aggregate von (SbF6)@[(A)9Ag11]11+ (x=7) oder (A)@[(A)12Ag12]12+ (x=8–10) wechselt. Die polykationischen Knoten stellen die ersten auf A und Silber basierenden Supersphären dar, die Wirt/Gast-fähig sind. Alle Produkte wurden durch NMR-Spektroskopie, Massenspektrometrie und Einkristall-Röntgenstrukturanalyse charakterisiert. Die Aggregate [(A)12Ag12]12+ wurden durch Transmissionselektronenmikroskopie visualisiert.
