New sandwich complexes of the type [bis(η6-arene)Ru][BF4]2, where the arenes are biphenyl, bibenzyl, fluorene, and trans-stilbene, have been synthesized. These complexes were prepared by reacting the [(acetone)3(η6-arene)Ru]2+ dication with the appropriate arene in refluxing trifluoroacetic acid. A crystal structure determination of the [(η6-biphenyl)2-Ru][BF4]2 complex establishes that the metal ion lies coordinated between two biphenyl ligands and binds in an η6 manner to one of the arene rings of each. The X-ray crystal structure of the [(η6-fluorene)2Ru][BF4]2 complex was also determined and found to be similar with respect to the coordination of the transition metal. However, in the fluorene complex two isomeric forms (syn and anti) were found to be present in the same lattice in equal proportion, differing principally with respect to the relative orientation of the methylene bridges.
