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

Abstract

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.
