Abstract

The reaction of Ag[C-5(CN)(5)] with anhydrous FeCl2 in acetonitrile leads to colourless crystals of tetrakis(acetonitrile-kappa N)bis(pentacyanocyclopentadienido- kappa N)iron(II) acetonitrile 1.8-solvate, [Fe(C10N5)(2)(CH3CN)(4)]center dot 1.8CH(3)CN or cis-[{C-5(CN)(5)}(2)(MeCN)(4)Fe]center dot 1.8MeCN. The compound crystallizes in the triclinic space group P (1) over bar as monomers, which exhibit weak C-H center dot center dot center dot N and pi-pi inter- actions. The crystals contain ca 20% solvent-accessible voids, which are nearly completely filled by two MeCN molecules.
