The first water-soluble hexarhenium cluster complexes with a heterocyclic ligand environment: synthesis, luminescence, and biological properties

The hexarhenium cluster complexes with benzotriazolate apical ligands [{Re6(μ3-Q)8}(BTA)6](4-) (Q = S, Se; BTA = benzotriazolate ion) were obtained by the reaction of [{Re6(μ3-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, elemental analyses, and UV-vis and luminescence spectroscopy. In addition, their cellular uptake and toxicity were evaluated. It was found that both clusters exhibited luminescence with high lifetimes and quantum yield values; they were taken up by the cells illuminating them under UV irradiation and, at the same time, did not exhibit acute cytotoxic effects.

3,3-Dimethyl-cis-9a,13a-diphenyl-2,3,9a,11,12,13a-hexa-hydro-1H-benzo[h][1,4]dioxino[2',3':5,6][1,4]dioxino[2,3-f]chromene

In the title di­hydro­dioxin, C₃₁H₂₈O₅, the dioxane ring has a chair conformation, whereas each of the pyran and dioxine rings has an envelope conformation with methyl­ene and quaternary C atoms, respectively, being the flap atoms. The phenyl rings are cis and form a dihedral angle of 82.11 (10)°. The molecular structure is stabilized by C—H⋯O contacts. In the crystal packing, supra­molecular layers parallel to (101) are sustained by C—H⋯π inter­actions.
