摘要

The dodecanuclear rhenium anionic complex with terminal hydroxo ligands [Re_(12)CS_(17)(OH)_6]~(6-) was obtained by the reaction of K_6[Re_(12)CS_(17)(CN) _6]·20H_2O with molten KOH at 300 °C. The cluster complex was crystallized as a potassium salt from aqueous solution. The reaction between K_6[Re_(12)CS_(17)(OH) _6]·4H_2O and Na_2S_2O _4 in water under reflux results in the formation of the complex Na_(12)[Re_(12)CS_(17)(SO_3) _6]·48.5H_2O. Both new compounds were characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. The electronic structure of [Re_(12)CS_(17)(OH)_6] ~(6-) was also elucidated by DFT calculations.
