The dinuclear complex cis-[(CH₃CN)₆Mo₂(O₂C-Fc)₂(BF₄)₂] (2) and the square-shaped compound [(CH₃CN)₄Mo₂(O₂C-Fc-CO₂)(BF₄)₂]₄ (3) can be synthesized by reacting [Mo₂(NCCH₃)₁₀][BF₄]₄ (1) with the corresponding ferrocenemonocarboxylic and -dicarboxylic acids (FMCA and FDCA) in a mixture of CH₃CN and THF. The reaction of [Mo₂(NCCH₃)₁₀] [BF₄]₄ (1) with tetrafluoroterephthalic acid in propionitrile solution affords the square-shaped complex [(CH₃CH₂CN)₄Mo₂(O₂C-C₆F₄-CO₂)(BF₄)₂]₄ (4). The interaction of 1 with 5-fluoroisophthalic acid using acetonitrile as solvent results in the isolation of the triangular complex [(CH₃CN)₆Mo₂(m-bdc-F)(BF₄)₂]₃ (5). The products 2鈥?b>5 have been characterized by single-crystal X-ray diffraction, NMR spectroscopy (¹H, ¹¹B, ¹³C, ¹⁹F), IR spectroscopy, elemental analysis, TG-MS, and UV鈥搗is spectroscopy measurements.
