Tricarbonyl(fulvene)chromium complexes, (C5H4CR2)Cr(CO)3, react with HgCl2 and SnCl4, respectively, to give stable 1:1 adducts.The metal basicity of the tricarbonyl(fulvene)chromium complexes is largely determined by the electronic properties of the substituents R at the exocyclic carbon atom of the fulvene ligand.The first crystalline protonation product of a fulvene complex was obtained by treatment of <η⁵-6,6-bis(dimethylamino)fulvene>Cr(CO)3 with HBF4.
