Abstract

Reactions of [{Re 6 Q 8 }Br 6 ] 4−/3− (Q = S, Se) with molten imidazole lead to the formation of two new neutral cluster complexes [{Re 6 Q 8 }(imzH) 4 (imz) 2 ] (imzH = imidazole). The interaction of [{Re 6 Q 8 }(imzH) 4 (imz) 2 ] with hydrohalic acids resulted in cationic complexes [{Re 6 Q 8 }(imzH) 6 ]X 2 (X = Cl, Br). All compounds were characterised by X-ray single-crystal and powder diffraction analyses, elemental analysis, energy dispersive X-ray and IR spectroscopies. The luminescence of the neutral compounds [{Re 6 Q 8 }(imzH) 4 (imz) 2 ] was also studied.
