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.
