Crystal structure of cyclic tris­(ferrocene-1,1′-di­yl)

The mol­ecular structure of the trinuclear title compound, [Fe3(C10H8)3] {systematic name: tris­[μ-(η5:η5)-1,1′-bi­cyclo­penta­dien­yl]tri­iron(II)}, consists of three ferrocene subunits (each with an eclipsed conformation) that are condensed via C—C bonds of the fulvalene moieties into a cyclic trimer. The angles between the planes of the cyclo­penta­dienyl (Cp) rings within the three fulvalene moieties are 76.1 (3), 80.9 (3) and 81.7 (3)°. In the crystal, C—H⋯π inter­actions between neighbouring mol­ecules lead to the cohesion of the structure.
