Abstract

The reactions between (Bu₄N)₂[{W₆I₈}I₆] (1) and silver carboxylates RCOOAg in CH₂Cl₂ afforded new luminescent carboxylate complexes (Bu₄N)₂[{W₆I₈}(RCOO)₆] [R = CH₃ (2), C₆H₅ (3), C₂F₅ (4), C₃F₇ (5), C₆F₅ (6)]. The complexes were characterized by single-crystal X-ray diffraction, elemental analysis, cyclic voltammetry, and IR and NMR spectroscopy. Complexes 1–6 all exhibit intense and long-lived photoluminescence. The carboxylate complexes undergo reversible electrochemical oxidation in two consecutive one-electron steps.
