N2 - Abstract: Octahedral rhenium cluster complexes of the composition [{Re 6(μ 3-Q) 8}(imz-[1,2-a]py) 6]Br 2, where Q = S, Se, are obtained by the interaction of Cs n[{Re 6(μ 3-Q 8)}Br 6] (n = 4 for Q = S; n = 3 for Q = Se) with an excess of imidazo-[1,2-а]pyridine in a sealed glass ampoule at 180 °С within two days. Both compounds are isostructural and crystallize in the trigonal space group R 3. The crystal structure of the complexes represents three differently directed chains of [{Re 6Q 8}(imz-[1,2-a]py) 6] 2+ cations and bromine anions linked with each other by С–H⋯Br⋯H–C hydrogen bonds. The compounds obtained have pronounced luminescence with emission maxima at 652 nm and 678 nm for Q = S, Se respectively.
