Abstract: Whereas the self-assembly of pentaphosphaferrocenes [Cp$^R$Fe(η$^5$-P$_5$)] (Cp$^R$ = Cp*, Cp$^×$, and Cp$^{Bn}$) with Cu and Ag salts has been well-studied in the past, the coordination chemistry toward Au complexes has been left untouched so far. Herein, the results of the self-assembly processes of [Cp$^R$Fe($η^5$-P$_5$)] with Au salts of different anions (GaCl$_4$$^–$, SbF$_6$$^–$, and Al(OC(CF$_3$)$_3$)$_4$ (TEF$^–$)) are reported. Next to a variety of molecular coordination products, the first coordination polymers based on polyphosphorus ligand complexes and Au salts are also obtained. Thereby, a 2D coordination polymer comprising metal vacancies is isolated. In all products, the Au centers are coordinated in a linear or a trigonal planar environment. In solution, highly dynamic processes are observed. Variable-temperature NMR spectroscopy, solid-state NMR spectroscopy, and X-ray powder diffraction were applied to gain further insight into selected coordination compounds.
