摘要：

A series of [Fe(eta-5-C5Ph5)(eta-6-arene)]+ complex cations [arene = benzene, toluene, o-, m- and p-xylene, mesitylene, durene (1,2,4,5-tetramethylbenzene) or hexamethylbenzene] is reported. The structure of the cation of the toluene derivative was determined by single-crystal X-ray diffraction [refined to R 0.034, R' 0.038 with 4328 data having I greater-than-or-equal-to 2.5-sigma(I)]. It crystallises from acetone as discrete molecules in the monoclinic space group P2(1)/n, with a = 10.016(2), b = 21.568(6), c = 16.920(4) angstrom, beta = 92.17(2)-degrees and Z = 4. The cyclopentadienyl ring binds in an eta-5 fashion and the Fe-C (C5 ring) bond distances average 2.093(3) angstrom; the Fe-C (C6 ring) bond distances average 2.113(4) angstrom. The Fe-C (C5 ring plane) and Fe-C (C6 ring plane) distances are 1.702(5) and 1.588(5) angstrom, respectively. All complexes exhibit two reversible reductions.
