Years ago, a large amount of H(CuBr2) was made by adding copper(I)-bromide to a concentrated hydrobromic acid solution in acetic acid. This reagent is used in Sandmeyer reaction, for replacing a diazo group to bromine on an aromatic ring.

The interesting thing in these crystals, that they are highly hygroscopic, deliquescent, so I had to photograph them in a closed glass tank. And the crystals are like a rubber, they could be easily squeezed, they wont break, just bend.
