Аннотация

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