Coordination chemistry of polynitriles. Part 9. Decacyanoferrocene revisited: crystal and molecular structure of cis-[{C₅(CN)₅}₂(MeCN)₄Fe].

ABSTRACT: The reaction of Ag[C₅(CN)₅] with anhydrous FeCl₂ in acetonitrile leads to colourless crystals of tetrakis(acetonitrile-κN)bis(pentacyanocyclopentadienido-κN)iron(II) acetonitrile 1.8-solvate, [Fe(C₁₀N₅)₂(CH₃CN)₄]·1.8CH₃CN or cis-[{C₅(CN)₅}₂(MeCN)₄Fe]·1.8MeCN. The compound crystallizes in the triclinic space group P-1 as monomers, which exhibit weak C-H...N and π-π interactions. The crystals contain ca 20% solvent-accessible voids, which are nearly completely filled by two MeCN molecules.
