Abstract
Two new cationic octahedral rhenium cluster complexes [{Re6Q8}(4-NH2-py)6]2+ (Q=S, Se; 4-NH2-py = 4-aminopyridine) were synthesized by reactions of cesium salts of cluster anions [{Re6Q8}Br6]4−/3− with molten 4-aminopyridine. Both complexes were separated as salts with Br− as counterions and the structure of [{Re6S8}(4-NH2-py)6]Br2·6DMF was revealed by X-ray single-crystal diffraction analysis. The compounds were characterized by elemental analysis, energy dispersive X-ray, IR, NMR, and luminescence spectroscopies.
