摘要：

Compound (H3O)(2)[{W6Br8}Br-6] center dot 4H(2)O is synthesized by the reaction of polymeric tungsten bromide W6Br12 with hydrobromic acid in an ethanolic solution. The structure of the compound is a packing of counterions H3O+ and [{W6Br8}Br-6](2-) and crystallization water molecules joined with each other by an extended system of hydrogen bonds. The finely crystalline sample of the complex exhibits luminescence, whose spectrum has a broad profile from similar to 500 nm to more than 950 nm with a maximum at similar to 715 nm, with an absolute quantum yield of similar to 0.225. The emission is characterized by the biexponential decay with lifetimes of similar to 2.2 and similar to 8.4 mu s.
