Abstract

The reaction of 1 equivalent of the dimolybdenum(II) complex [Mo₂(NCCH₃)₁₀][BF₄]₄ (1) with tetrabromoterephthalic acid (0.5 equiv.) in acetonitrile or propionitrile affords the dimeric dicarboxylate-bridged complexes [(CH₃CN)₈Mo₂(OOC-C₆Br₄-COO)Mo₂(NCCH₃)₈][BF₄]₆ (2) and [(CH₃CH₂CN)₈Mo₂(OOC-C₆Br₄-COO)Mo₂(NCCH₂CH₃)₈][BF₄]₆ (3), respectively. The molecular square [(CH₃CN)₆Mo₂(OOC-C₄H₂S-COO)]₄[BF₄]₈ (4) can be isolated by reacting [Mo₂(NCCH₃)₁₀][BF₄]₄ (1) (1 equiv.) with 2,5-thiophenedicarboxylic acid (1 equiv.) in acetonitrile. The isolated coordination compounds 2-4 are characterized by NMR spectroscopy (¹H, ¹¹B, ¹³C{¹H}, ¹⁹F), IR spectroscopy, elemental analysis, TG-MS measurements and UV-Vis spectroscopy. The molecular structures of compounds 2 and 4 are determined by X-ray single crystal diffraction.
