[Co(NH₃)₅(H₂O)]Br₃ : Aquopentaamminecobalt(III) tribromide
Cobalt atom coordinated in an octahedral geometry to 5 NH₃ and one water ligands. All bromides are not coordinating.

[Co(NH₃)₅Br]Br₂ : Bromopentaamminecobalt(III) dibromide
Cobalt atom coordinated in an octahedral geometry to 5 NH₃ and one bromide ligands. Two bromides are not coordinating.
