It is similar to that of triiodide ion.

Actually bromine is a member of group VII A. It has 7 electrons in its valence shell, two electrons are contributed by the neighboring bromine atoms which form covalent bond with the central bromine atom. There is negative charge also which makes the total electron count of 10 i.e. 5 electron pairs need to be arranged around the central bromide ion.

This gives to trigonal bipyramidal structure.

The bond pairs are arranged in a linear fashion while the lone pairs occupy the trigonal places.
