Abstract:
Compound (H3O)2[{W6Br8}Br6] · 4H2O 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}Br6]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 ∼500 nm to more than 950 nm with a maximum at ∼715 nm, with an absolute quantum yield of ∼0.225. The emission is characterized by the biexponential decay with lifetimes of ∼2.2 and ∼8.4 μs.
