Cover illustration: The binuclear compound {μ-2,2′-(ethane-1,2-di­yl)bis­[4,6-bis­(tri­methyl­sil­yl)-1,3-di­hydro­cyclo­penta­[c]pyrrol-5-one]}bis­[tri­carbonyl­iron(0)], [Fe2(C28H48N2O2Si4)(CO)6], consists of two central iron(0) atoms, each of them surrounded by a cyclo­penta­dienone moiety and three carbonyl ligands in a three-legged piano-stool shape. Furthermore, the bis­(cyclo­penta­dienone) ligand acts as a bridge between the two metal atoms. See: Huerta-Zerón, Spannenberg, Beller & Junge [IUCrData (2023). 8, x230346].
