Octahedral rhenium cluster complexes with organic ligands: Synthesis, structure and properties of [Re6Q8(3,5-Me2PzH)6]Br2 · 2(3,5-Me2PzH) (Q = S, Se)

Two new octahedral cluster complexes – [Re6S8(3,5-Me2PzH)6]Br2 · 2(3,5-Me2PzH) (1) and [Re6Se8(3,5-Me2PzH)6]Br2 · 2(3,5-Me2PzH) (2), where 3,5-Me2PzH is 3,5-dimethylpyrazole, have been synthesized using reaction of rhenium chalcobromide complexes Cs4[Re6S8Br6] · 2H2O and Cs3[Re6Se8Br6] · H2O, respectively, with molten 3,5-dimethylpyrazole. Both compounds synthesized were characterized by X-ray single-crystal diffraction and chemical analysis, IR and luminescent spectra.
