Whereas the self-assembly of pentaphosphaferrocenes [CpFe(η-P)] (Cp = Cp*, Cp, and Cp) 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(η-P)] with Au salts of different anions (GaCl, SbF, and Al(OC(CF)) (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.

The products comprise unprecedented all-cis tripodal triphosphino-cyclotriphosphine ligands. The iodination of [Cp*Fe(η -As )] (6) gave, in addition to [Fe(CH CN) ] salts of the rare [As I ] (in 7) and [As I ] (in 8) anions, the first di-cationic Fe-As triple decker complex [(Cp*Fe) (μ,η -As )][As I ] (9).

Herein, we present the use of a triple decker complex as template that leads to the formation of unprecedented 'nano-bowls'. These spherical domes resemble the truncated fullerenes -C and represent a novel spherical arrangement in the chemistry of spherical molecules.

Here, the self-assembly of 1 a with Cu and Cu halides in the presence of the template complexes [FeCp ][PF ], [CoCp ][PF ] and [CoCp ] is reported, testifying to the redox behavior of the formed supramolecules. The oxidation or reduction capacity of these reactive complexes does not inhibit their template impact and, for the first time, the cationic metallocene [CoCp ] is enclosed in unprecedented anionic organometallic hosts.
