Abstract: One-pot self-assembly reactions of the polyphosphoruscomplex [Cp*Fe($\eta^5$-P$_5$)] (A), a coinage metal saltAgSbF$_6$, and flexible aliphatic dinitriles NC(CH$_2$)$_x$CN (x=1–10) yield 1D, 2D, and 3D coordination polymers. The sevenmemberedbackbone of the dinitrile was experimentally foundas the borderline for the self-assembly system furnishingproducts of different kinds. At x<7, various rather simplepolymers are exclusively formed possessing either 0D or 1DAg/A structural motifs connected by dinitrile spacers, while at x$\geq$+7, the self-assembly switches to unprecedented extraordinary3D networks of nano-sized host–guest assemblies(SbF$_6$)@[(A)$_9$Ag$_{11}$]$^{11+}$ (x=7) or (A)@[(A)$_{12}$Ag$_{12}$]$^{12+}$ (x=8–10) linked by dinitriles. The polycationic nodes represent thefirst superspheres based on A and silver and are host–guestable. All products are characterized by NMR spectroscopy,mass spectrometry, and single-crystal X-ray diffraction. Theassemblies [(A)$_{12}$Ag$_{12}$]$^{12+}$ were visualized by transmissionelectron microscopy.
