Zusammenfassung

The coordination chemistry of 1,1‘-diisocyanoferrocene (1) was investigated. Its reaction with Cr(CO)5(THF) (2 equiv) affords (1)[Cr(CO)5]2, which exhibits eclipsed cyclopentadienyl rings with a synclinal arrangement of the two substituents. 1 behaves like an aryl isocyanide in this compound according to IR spectroscopic data, and its oxidation leads to a marked decrease of net electron donor ability. The reaction of 1 with AuCl(SMe2) affords the insoluble coordination polymer [(1)(AuCl)2]∞. The (1)(AuCl)2 molecules adopt a 3,4-diaura-[6]ferrocenophane structure. They are aggregated in a zipperlike fashion through aurophilic interactions, with Au−Au distances ranging from 3.34 to 3.48 Å. The adsorption of 1 from acetonitrile solution on polycrystalline gold affords a self-assembled monolayer. Both isocyanide groups are binding to the surface.
