Developed was a systematic method for the incorporation of the {(eta(6)-arene)Fe} fragment into a carborane cage. Reactions between [(eta(6)-arene)(2)Fe](PF6)(2) salts and Tl-2[nido-7,8-C2B9H11] in refluxing (CH2)(2)Cl-2 generated a series of [3-(eta(6)-arene)-closo-3,1,2-FeC2B9H11] neutral complexes with variable types of polymethylated arene ligands in the structure. The structures of durene and hexamethylbenzene complexes were established by X-ray diffraction analyses. The work also shows that the original hi temperature method for the preparation of the [(eta(6)-arene)(2)Fe](2+) dications fails for mesitylene and durene compounds, which was overcome by a reliable room-temperature modification.
