Whereas the self-assembly of pentaphosphaferrocenes [(CpFe)-Fe-R(eta(5)-P-5)] (Cp-R = Cp*, Cp-x, 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 [(CpFe)-Fe-R(eta(5)-P-5)] with Au salts of different anions (GaCl4-, SbF6-, and Al(OC(CF3)(3))(4) ...

Whereas the self-assembly of pentaphosphaferrocenes [(CpFe)-Fe-R(eta(5)-P-5)] (Cp-R = Cp*, Cp-x, 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 [(CpFe)-Fe-R(eta(5)-P-5)] with Au salts of different anions (GaCl4-, SbF6-, and Al(OC(CF3)(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.
