The dodecanuclear rhenium anionic complex with terminal hydroxo ligands [Re12CS17(OH)6]6- was obtained by the reaction of K6[Re12CS17(CN) 6]·20H2O with molten KOH at 300 °C. The cluster complex was crystallized as a potassium salt from aqueous solution. The reaction between K6[Re12CS17(OH) 6]·4H2O and Na2S2O 4 in water under reflux results in the formation of the complex Na12[Re12CS17(SO3) 6]·48.5H2O. Both new compounds were characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. The electronic structure of [Re12CS17(OH)6] 6- was also elucidated by DFT calculations.
