Abstract

Four new octahedral rhenium cluster complexes trans-[{Re6Q8}(PPh3)4X2] (Q=S, Se; X=Cl, I) were synthesized by reaction of cesium salts of cluster anions [{Re6Q8}X6]4−/3− with molten triphenylphosphine. The compounds were characterized by elemental and X-ray structural analyses. Emission spectra and photophysical characteristics for all new compounds and earlier described trans-[{Re6Q8}(PPh3)4Br2] were obtained showing a dependence of the emission maximum wavelength, quantum yield and lifetime values from cluster ligand environment.
