文摘

Herein we report the synthesis of a series of iron-functionalized, mixed-valent, polyoxovanadate alkoxide clusters, [V₅O₆(OCH₃)₁₂Fe]X (X = Cl, Br, SO₃CF₃) comprised of a hexanuclear Lindqvist (M₆O₁₉^n–) core. By substituting a V═O moiety from the well-defined hexavanadate clusters [V^IV_nV^V_6–nO₇(OR)₁₂]^4–n (R = Me, Et) with a metal cation, we have developed a novel template for investigation of the organometallic properties of these systems. Characterization of the clusters was performed by ¹H NMR, Fourier transform infrared, and electron absorption spectroscopies and electrospray ionization mass spectrometry. The IR and UV–vis spectra suggest substantial electronic delocalization, similar to the previously reported cluster, V₆O₇(OCH₃)₁₂.
