Abstract: The so far missing parent compound of the large family of pentaphosphaferrocenes [(C$_{5}$H$_{5}$)Fe($η^{5}‐P_{5})]$ (1 b) was synthesized by the thermolysis of [CpFe(CO)$_2$]$_2$ with P$_4$ using the very high-boiling solvent diisopropylbenzene. It was comprehensively characterized by, inter alia, NMR spectroscopy, single crystal X-ray structure analysis, cyclic voltammetry and DFT computations. Moreover, its coordination behavior towards CuI halides was explored, revealing the unprecedented 2D polymeric networks [{CpFe($η^{5:1:1:1:1}$-P$_5$)}Cu$_2$(μ-X)$_2$]$_n$ (2 a: X=Cl, 2 b: X=Br) and [{CpFe($η^{5:1:1}$-P$_5$)}Cu(μ-I)]$_n$ (3) and even the first cyclo-P5-containing 3D coordination polymer [{CpFe($η^{5:1:1}$-P$_5$)}Cu(μ-I)]$_n$ (4). The sandwich complex 1 b can also be incorporated in nano-sized supramolecules based on [Cp*Fe($η^5 -P_5$)] (1 a) and CuX (X=Cl, Br, I): [CpFe($η^5 -P_5$)]@[{Cp*Fe($η^5 -P_5$)}$_{12}$(CuX)$_{20-n}$] (5 a: X=Cl, n=2.4; 5 b: X=Br, n=2.4; 5 c: X=I, n=0.95). Thereby, the formation of the CuI-containing fullerene-like sphere 5 c is found for the first time.
