title: (μ-Ethane-1,2-diamine-κN:N')bis-[dicarbon-yl(η-cyclo-penta-dien-yl)iron(II)] bis-(tetra-fluorido-borate).
abstract: The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along with weak C-H⋯O and C-H⋯F inter-actions.
