The hexarhenium cluster complexes with benzotriazolate apical ligands [{Re63-Q)8}(BTA)6]4− (Q = S or Se; BTA = benzotriazolate ion) were obtained by a reaction of [{Re63-Q)8}(OH)6]4− with molten 1H-BTA (1H-benzotriazole). The clusters were crystallized as potassium salts and characterized by X-ray single-crystal diffraction and elemental analyses, UV-vis and luminescence spectroscopies. Also, their cellular uptake and toxicity were evaluated. It was found that the both clusters exhibiting luminescence with high lifetimes and quantum yield values were taken up by the cells illuminating them under UV and, at the same time, did not exhibit acute cytotoxic effects.
