Abstract

New octahedral anionic heterometal rhenium-osmium cluster complexes [Re ₅OsSe ₈(OH) ₆] ^3- and [Re ₄Os ₂Se ₈(OH) ₆] ^2- were synthesized starting from [Re ₅OsSe ₈Cl ₆] ^3- and [Re ₄Os ₂Se ₈Cl ₆] ^2-, respectively. They were isolated as salts of the compositions Cs ₃[Re ₅OsSe ₈(OH) ₆] · 11H ₂O (I), K ₃[Re ₅OsSe ₈(OH) ₆] · 7H ₂O (II), and K ₂[Re ₄Os ₂Se ₈(OH) ₆] · 3H ₂O (III). The protonation of the terminal OH ligands of [Re ₅OsSe ₈(OH) ₆] ^3- in an aqueous solution resulted in crystallization of a neutral complex [Re ₅OsSe ₈(H ₂O) ₃(OH) ₃] · 12H ₂O (IV). The compounds have been characterized by single-crystal X-ray diffraction analysis. The luminescence properties of [Re ₅OsSe ₈(OH) ₆] ^3- and [Re ₄Os ₂Se ₈(OH) ₆] ^2- were studied. In addition, the electronic structures of the complexes were elucidated by DFT calculations.
